Optimal and Long-Term Dynamic Transport Policy Design: Seeking Maximum Social Welfare through a Pricing Scheme

This article presents an alternative approach to the decision-making process in transport strategy design. The study explores the possibility of integrating forecasting, assessment and optimization procedures in support of a decision-making process designed to reach the best achievable scenario through mobility policies. Long-term evaluation, as required by a dynamic system such as a city, is provided by a strategic Land-Use and Transport Interaction (LUTI) model. The social welfare achieved by implementing mobility LUTI model policies is measured through a cost-benefit analysis and maximized through an optimization process throughout the evaluation period. The method is tested by optimizing a pricing policy scheme in Madrid on a cordon toll in a context requiring system efficiency, social equity and environmental quality. The optimized scheme yields an appreciable increase in social surplus through a relatively low rate compared to other similar pricing toll schemes. The results highlight the different considerations regarding mobility impacts on the case study area, as well as the major contributors to social welfare surplus. This leads the authors to reconsider the cost-analysis approach, as defined in the study, as the best option for formulating sustainability measures.

Modelo para evaluar el capital social en programas de cooperación para el desarrollo

Los programas de desarrollo regional promovidos por los gobiernos nacionales y las agencias multilaterales, como el Banco Mundial y el Banco Interamericano de Desarrollo (BID), se orientan a las políticas públicas de suministro de bienes públicos, ya sean servicios públicos o infraestructuras, a las regiones subdesarrolladas. Las evidencias apuntan que el éxito de estos programas depende en parte de externalidades, las cuales se relacionan con los cambios del tejido asociativo y los valores de los participantes de la comunidad. Estas externalidades se definen como el capital social. Cómo las externalidades no son directamente evaluadas en el impacto económico y social de los proyectos, pero su existencia es aceptada por los planificadores que reconocen la importancia de desarrollar el tejido de relaciones en la comunidad. Sin embargo este capital social no es medido. El objeto de esta tesis es investigar y proponer procesos de medida y evaluación del capital social de un proyecto, y relacionarlos con las actividades del mismo en un territorio y proyecto dado como casos de estudio. El Programa de Desarrollo de la Zona de Mata (PROMATA) en el Estado de Pernambuco, Brasil, financiado por el Estado de Pernambuco en Brasil y el BID, finalizado en 2010, ha sido elegido como caso de estudio. Para la evaluación y medida del capital social se han estudiado dos periodos. Uno considerando solo los planes del proyecto, sin considerar su implantación, que se ha denominado evaluación A Priori, basada en un panel de expertos con visión de las externalidades generadas. Y otra con la participación de las partes de la comunidad después de su finalización, denomina evaluación A Posteriori, para lo cual se han entrevistado un número significativo de partes interesadas utilizando un cuestionario especialmente diseñado. Los resultados han sido procesados mediante análisis estadísticos avanzados. El proyecto PROMATA es considerado un caso de éxito en Brasil, en parte por su aproximación al desarrollo asociativo. Sin embargo las valoraciones del capital social muestran que algunas relaciones Estado-sociedad y sociedad-personas no han cambiado todo lo esperado, en oposición a las evaluaciones de satisfacción de los indicadores del proyecto. Es el efecto externo del capital social. ABSTRACT The regional development programs promoted by the national governments and international multilateral agencies, like the World Bank and the Interamerican Development Bank (BID), are oriented to public policies under which public goods, like public services and infrastructures, are supplied to underdeveloped regions. More and more evidences are pointing to the fact that success of these programs depends in a good part of externalities, which are related to the changes in the networking and values among the stakeholders in the territory. These externalities are defined as the Social Capital. As externalities, they are not directly evaluated in the projects economic and social impact, but accepted to exist and the planners of the projects do acknowledge the important of social networking. However never assessed. The objective of this thesis is to investigate and propose a way to measure and assess the social capital of a given project, and relate that with the activities of the project, with a given project and territory as base case. The Development Program in Zona da Mata (PROMATA) in the State of Pernambuco, Brazil, funded by the Brazil State and the BID, ended in 2010, was chosen as the base case. For the assessment of the social capital two periods in time where studied. One considering only the project program named a priori evaluation and based in a panel of experts, which are aware of the possible externalities of the project. Other, considering the stakeholders view after the project ended, named posterior evaluation, which required interviewing a number of stakeholders using a specially designed questionnaire. The results were processed using advanced statistical techniques. PROMATA is considered a success case story in Brazil, in part for its social networking approach. However when the social capital is assessed there are areas of state-society and society-community relations not that well transformed, as the satisfaction research of the project indicators. This unforeseen externality is the social capital effect.

The role of rehabilitation of building in the urban integration, social cohesion and environmental responsibility

In the framework ofthe National Research Plan2008-2011, our research poses estrategy for the design and evaluation of plans and programmes of urban integrated regeneration. The objective is to develop a study on the role of rehabilitation of buildings in concepts like urban integration, social cohesion and environmental responsibility. The research proposes a methodological tool for evaluating urban regeneration processes from a holistic perspective that can serve as a guide for governments and technical teams to address intervention in consolidated urban areas with physical and socio-economic problems. The development of the tool has inevitably led to delve into different areas where you can intervene but has not lost sight of the complex interplay of factors involved in the process.It is an open source tool to visualize Urban Integrated Rehabilitation processes.

Novel educational assessment for building structures: Automatic evaluation of on-line graphics

This article presents a new automatic evaluation for on-line graphics, its application and the numerous advantages achieved applying this developed correcting method. The software application developed by the Innovation in Education Group “E4”, from the Technical University of Madrid, is oriented for the online self-assessment of the graphic drawings that students carry out as continuous training. The adaptation to the European Higher Educational Area is an important opportunity to research about the possibilities of on-line education assessment. In this way, a new software tool has been developed for continuous self-testing by undergraduates. Using this software it is possible to evaluate the graphical answer of the students. Thus, the drawings made on-line by students are automatically corrected according to the geometry (straight lines, sloping lines or second order curves) and by sizes (depending on the specific values which define the graphics).

Design, development and evaluation of a portable recording system to capture dynamic presentations using the teacher's tablet PC

Computers and multimedia equipment have improved a lot in the last years. They have reduced their cost and size while at the same time increased their capabilities. These improvements allowed us to design and implement a portable recording system that also integrates the teacher´s tablet PC to capture what he/she writes on the slides and all that happens in it. This paper explains this system in detail and the validation of the recordings that we did after using it to record all the lectures the “Communications Software” course in our university. The results show that pupils used the recordings for different purposes and consider them useful for a variety of things, especially after missing a lecture.

Evaluating the spatial and social equity effects of road pricing in the European urban context: the Madrid Metropolitan Area.

The paper explores the spatial and social impacts arising from implementation of a road-pricing scheme in the Madrid Metropolitan Area (MMA). Our analytical focus is on understanding the effects of the scheme on the transport accessibility of different social groups within the MMA. We define an evaluation framework to appraise the accessibility of different districts within the MMA in terms of the actual and perceived cost of using the road infrastructure "before" and "after" the implementation of the scheme. The framework was developed using quantitative survey data and qualitative data from focus group discussions with residents. We then simulated user behaviors (mode and route choice) based on the empirical evidence from a travel demand model for the MMA. The results from our simulation model demonstrated that implementation of the toll on the orbital metropolitan motorways (M40, M30, for example) decreases accessibility, mostly in the districts where there are no viable public transport alternatives. Our key finding is that the economic burden of the road-pricing scheme particularly affects unskilled and lower income individuals living in the south of the MMA. Consequently lower income people reduce their use of tolled roads and have to find new arrangements for these trips: i.e. switch to the public transport, spend double the time for their commuter trips or stay at home. The results of our research could be applicable more widely for anyone wishing to better understand the important relationship between increased transport cost and social equity, especially where there is an intention to introduce similar road-pricing schemes within the urban context.

Evaluating the quality of riparian forest vegetation: The Riparian Forest Evaluation (RFV) index

Aim of study: This paper presents a novel index, the Riparian Forest Evaluation (RFV) index, for assessing the ecological condition of riparian forests. The status of riparian ecosystems has global importance due to the ecological and social benefits and services they provide. The initiation of the European Water Framework Directive (2000/60/CE) requires the assessment of the hydromorphological quality of natural channels. The Directive describes riparian forests as one of the fundamental components that determine the structure of riverine areas. The RFV index was developed to meet the aim of the Directive and to complement the existing methodologies for the evaluation of riparian forests. Area of study: The RFV index was applied to a wide range of streams and rivers (170 water bodies) inSpain. Materials and methods: The calculation of the RFV index is based on the assessment of both the spatial continuity of the forest (in its three core dimensions: longitudinal, transversal and vertical) and the regeneration capacity of the forest, in a sampling area related to the river hydromorphological pattern. This index enables an evaluation of the quality and degree of alteration of riparian forests. In addition, it helps to determine the scenarios that are necessary to improve the status of riparian forests and to develop processes for restoring their structure and composition. Main results: The results were compared with some previous tools for the assessment of riparian vegetation. The RFV index got the highest average scores in the basins of northernSpain, which suffer lower human influence. The forests in central and southern rivers got worse scores. The bigger differences with other tools were found in complex and partially altered streams and rivers. Research highlights: The study showed the index’s applicability under diverse hydromorphological and ecological conditions and the main advantages of its application. The utilization of the index allows a better understanding of the status of riparian forests, and enhances improvements in the conservation and management of riparian areas.

This project of formative research involving civil and academic initiative is based on a diagnostic method and participative design for the evaluation and intervention of Pamplona‘s architectural and urban heritage, specifically applied to the design of public space, in its historical center, based in the relationship that is built between the architects in formation and the community.

Métodos diferenciales e interferométricos para la evaluación de deformaciones de la corteza terrestre mediante técnicas GNSS e InSAR = Differential and interferometric methods for evaluation of crustal deformation using GNSS and InSAR techniques

La actividad volcánica interviene en multitud de facetas de la propia actividad humana, no siempre negativas. Sin embargo, son más los motivos de peligrosidad y riesgo que incitan al estudio de la actividad volcánica. Existen razones de seguridad que inciden en el mantenimiento del seguimiento y monitorización de la actividad volcánica para garantizar la vida y la seguridad de los asentamientos antrópicos en las proximidades de los edificios volcánicos. En esta tesis se define e implementa un sistema de monitorización de movimientos de la corteza en las islas de Tenerife y La Palma, donde el impacto social que representa un aumento o variación de la actividad volcánica en las islas es muy severo. Aparte de la alta densidad demográfica del Archipiélago, esta población aumenta significativamente, en diferentes periodos a lo largo del año, debido a la actividad turística que representa la mayor fuente de ingresos de las islas. La población y los centros turísticos se diseminan predominantemente a lo largo de las costas y también a lo largo de los flancos de los edificios volcánicos. Quizá el mantenimiento de estas estructuras sociales y socio-económicas son los motivos más importantes que justifican una monitorización de la actividad volcánica en las Islas Canarias. Recientemente se ha venido trabajando cada vez más en el intento de predecir la actividad volcánica utilizando los nuevos sistemas de monitorización geodésica, puesto que la actividad volcánica se manifiesta anteriormente por deformación de la corteza terrestre y cambios en la fuerza de la gravedad en la zona donde más tarde se registran eventos volcánicos. Los nuevos dispositivos y sensores que se han desarrollado en los últimos años en materias como la geodesia, la observación de la Tierra desde el espacio y el posicionamiento por satélite, han permitido observar y medir tanto la deformación producida en el terreno como los cambios de la fuerza de la gravedad antes, durante y posteriormente a los eventos volcánicos que se producen. Estos nuevos dispositivos y sensores han cambiado las técnicas o metodologías geodésicas que se venían utilizando hasta la aparición de los mismos, renovando métodos clásicos y desarrollando otros nuevos que ya se están afianzando como metodologías probadas y reconocidas para ser usadas en la monitorización volcánica. Desde finales de la década de los noventa del siglo pasado se han venido desarrollando en las Islas Canarias varios proyectos que han tenido como objetivos principales el desarrollo de nuevas técnicas de observación y monitorización por un lado y el diseño de una metodología de monitorización volcánica adecuada, por otro. Se presenta aquí el estudio y desarrollo de técnicas GNSS para la monitorización de deformaciones corticales y su campo de velocidades para las islas de Tenerife y La Palma. En su implementación, se ha tenido en cuenta el uso de la infraestructura geodésica y de monitorización existente en el archipiélago a fin de optimizar costes, además de complementarla con nuevas estaciones para dar una cobertura total a las dos islas. Los resultados obtenidos en los proyectos, que se describen en esta memoria, han dado nuevas perspectivas en la monitorización geodésica de la actividad volcánica y nuevas zonas de interés que anteriormente no se conocían en el entorno de las Islas Canarias. Se ha tenido especial cuidado en el tratamiento y propagación de los errores durante todo el proceso de observación, medida y proceso de los datos registrados, todo ello en aras de cuantificar el grado de fiabilidad de los resultados obtenidos. También en este sentido, los resultados obtenidos han sido verificados con otros procedentes de sistemas de observación radar de satélite, incorporando además a este estudio las implicaciones que el uso conjunto de tecnologías radar y GNSS tendrán en un futuro en la monitorización de deformaciones de la corteza terrestre. ABSTRACT Volcanic activity occurs in many aspects of human activity, and not always in a negative manner. Nonetheless, research into volcanic activity is more likely to be motivated by its danger and risk. There are security reasons that influence the monitoring of volcanic activity in order to guarantee the life and safety of human settlements near volcanic edifices. This thesis defines and implements a monitoring system of movements in the Earth’s crust in the islands of Tenerife and La Palma, where the social impact of an increase (or variation) of volcanic activity is very severe. Aside from the high demographic density of the archipelago, the population increases significantly in different periods throughout the year due to tourism, which represents a major source of revenue for the islands. The population and the tourist centres are mainly spread along the coasts and also along the flanks of the volcanic edifices. Perhaps the preservation of these social and socio-economic structures is the most important reason that justifies monitoring volcanic activity in the Canary Islands. Recently more and more work has been done with the intention of predicting volcanic activity, using new geodesic monitoring systems, since volcanic activity is evident prior to eruption because of a deformation of the Earth’s crust and changes in the force of gravity in the zone where volcanic events will later be recorded. The new devices and sensors that have been developed in recent years in areas such as geodesy, the observation of the Earth from space, and satellite positioning have allowed us to observe and measure the deformation produced in the Earth as well as the changes in the force of gravity before, during, and after the volcanic events occur. The new devices and sensors have changed the geodetic techniques and methodologies that were used previously. The classic methods have been renovated and other newer ones developed that are now vouched for as proven recognised methodologies to be used for volcanic monitoring. Since the end of the 1990s, in the Canary Islands various projects have been developed whose principal aim has been the development of new observation and monitoring techniques on the one hand, and the design of an appropriate volcanic monitoring methodology on the other. The study and development of GNSS techniques for the monitoring of crustal deformations and their velocity field is presented here. To carry out the study, the use of geodetic infrastructure and existing monitoring in the archipelago have been taken into account in order to optimise costs, besides complementing it with new stations for total coverage on both islands. The results obtained in the projects, which are described below, have produced new perspectives in the geodetic monitoring of volcanic activity and new zones of interest which previously were unknown in the environment of the Canary Islands. Special care has been taken with the treatment and propagation of errors during the entire process of observing, measuring, and processing the recorded data. All of this was done in order to quantify the degree of trustworthiness of the results obtained. Also in this sense, the results obtained have been verified with others from satellite radar observation systems, incorporating as well in this study the implications that the joint use of radar technologies and GNSS will have for the future of monitoring deformations in the Earth’s crust.

Local relevance evaluation in the accreditation bodies for engineering masters programs

Accreditation models in the international context mainly consider the evaluation of learning outcomes and the ability of programs (or higher education institutions) to achieve the educational objectives stated in their mission. However, it is not clear if these objectives and therefore their outcomes satisfy real national and regional needs, a critical point in engineering master's programs, especially in developing countries. The aim of this paper is to study the importance of the local relevancy evaluation of these programs and to analyze the main models of quality assurance and accreditation bodies of USA, Europe and Latin America, in order to ascertain whether the relevancy is evaluated or not. After a literature review, we found that in a free-market economic context and international education, the accreditation of master's programs follows an international accreditation model, and doesńt take in account in most cases criteria and indicators for local relevancy. It concludes that it is necessary both, international accreditation to ensure the effectiveness of the program (achievement of learning outcomes) and the national accreditation through which it could ensure local relevancy of programs, for which we are giving some indicators.

Relevance evaluation of engineering masters program in Peru

In a context of mass higher education, it is necessary to ensure not only quality but also the relevance of engineering master's programs, namely the appropriateness of the objectives and outcomes to the needs and interests of the program beneficiaries. After a literature review we analyzed the evaluation models of three organizations in Peru: the Board of Evaluation, Accreditation and Certification of the University Education Quality CONEAU, the Institute of Quality and Accreditation of Computing, Engineering and Technology - ICACIT and the Pontificia Universidad Catolica del Peru. The result of this study is a model for relevance evaluation for an engineering master¿s program in Peru.

Empowerment Evaluation in Spain: The Critical Friend Role in Working with Rural Communities

Rural communities in Cuenca (Spain) are characterized by a great social dislocation, mostly due to the low population density in these areas. In this way, the existence of groups of citizens able to be active agents of their development process is a critical aspect for any community-based development process in this Spanish region. The Institute of Community Development of Cuenca (IDC) has been working with this type of groups for the last 30 years focusing on the organizational empowerment of the rural communities. Main tools in this process have been the empowerment evaluation approach and the critical friend role when helping the groups to achieve their objectives and reinforcing them. This chapter analyses the empowerment process and how the critical friend role is nourished by the facilitator figure.

A INFLUÊNCIA DA QUALIDADE DE VIDA E SUPORTE SOCIAL NO ABSENTEÍSMO POR LESÕES OCUPACIONAIS

Esta pesquisa é uma proposta de aproximação das diversas áreas de conhecimento e flexibilização de suas fronteiras, a fim de estabelecer interfaces entre os diversos campos conceituais engendrando novas práticas que ensejam formas mais abrangentes e holísticas de aproximação com a realidade. Através da avaliação da qualidade de vida, suporte social e sua relação com o absenteísmo por lesão ocupacional. Materiais e Métodos: Participaram desta pesquisa 47 trabalhadores, do sexo masculino, com idade variável entre 30 e 60 anos, que trabalham no setor de centrifugação dentro de uma fundição em uma indústria metalúrgica do ramo de autopeças em São Bernardo do Campo. Instrumentos: Foi analisado o prontuário médico de cada um desses trabalhadores, sendo analisadas como variáveis: se esses trabalhadores apresentaram lesões ocupacionais avaliadas e diagnosticadas pelos médicos. Avaliação de um questionário social, composto por quatro questões abertas: idade, nível de escolaridade, estado civil e número de dependentes. Instrumento de Avaliação da Qualidade de Vida WHOQOL Bref. e Instrumento de Avaliação de Suporte Social: Escala de percepção de suporte social (EPSS). Análise dos Resultados: Os dados coletados dos prontuários foram agrupados em quatro grupos chamados de: grupo de absenteísmo 1, grupo de absenteísmo 2, grupo de absenteísmo 3 e grupo de absenteísmo 4. Sendo o primeiro composto por 15 trabalhadores que não apresentaram lesões ocupacionais. O segundo grupo composto por 10 trabalhadores apresentou de uma hora até seiscentas horas de absenteísmo por lesão ocupacional. O terceiro grupo composto por 11 trabalhadores apresentou absenteísmo de seiscentas e uma horas até mil horas, e o quarto grupo constituído de 11 trabalhadores tiveram absenteísmo superior a mil horas. Resultados: Nas comparações entre os grupos de absenteísmo e as variáveis do questionário social não foram encontradas diferenças significantemente estatística, o mesmo tendo ocorrido na comparação entre grupos de absenteísmo e os escores do EPSS Analisando os grupos de absenteísmo e os domínios do WHOQOL Bref. Foi detectada diferença com significância estatística de P = 0,01 maior dentro do domínio físico no grupo de absenteísmo 1 que não apresentou absenteísmo em relação ao grupo de absenteísmo 4 com maior número de absenteísmo. Conclusão: Visto que as lesões ocupacionais interferem na qualidade de vida dos indivíduos, o que se pode constatar é que o modelo biomédico ainda é muito forte, principalmente dentro da saúde ocupacional que na busca de soluções ergonômicas defronta com os interesses econômicos imediatistas que não contemplam os investimentos indispensáveis à garantia da saúde do trabalhador. Sintetizando as análises conceituais e os resultados deste trabalho, mostrou-se que os problemas de saúde ocupacional são conhecidos há muito tempo. Apesar da crescente produção de trabalhos acerca da construção , conhecimento das características da saúde do trabalhador e a existência de uma tônica predominante que sugere a mudança das situações encontradas, há um escasso empenho em efetuar as transformações necessárias, num descompasso entre avanço do conhecimento e perpetuação de práticas insalubres. Para tanto é necessária uma compreensão das determinantes da saúde. Além do investimento material se faz necessário emergir um verdadeiro diálogo entre as ciências. Ressalta-se a necessidade de estudos longitudinais para elucidar a complexidade das relações entre qualidade de vida, suporte social e lesões ocupacionais. Os achados apontam para a relevância de estudos futuros acerca dessas associações.(AU)

Low-status monkeys “play dumb” when learning in mixed social groups

Many primates, including humans, live in complex hierarchical societies where social context and status affect daily life. Nevertheless, primate learning studies typically test single animals in limited laboratory settings where the important effects of social interactions and relationships cannot be studied. To investigate the impact of sociality on associative learning, we compared the individual performances of group-tested rhesus monkeys (Macaca mulatta) across various social contexts. We used a traditional discrimination paradigm that measures an animal’s ability to form associations between cues and the obtaining of food in choice situations; but we adapted the task for group testing. After training a 55-member colony to separate on command into two subgroups, composed of either high- or low-status families, we exposed animals to two color discrimination problems, one with all monkeys present (combined condition), the other in their “dominant” and “subordinate” cohorts (split condition). Next, we manipulated learning history by testing animals on the same problems, but with the social contexts reversed. Monkeys from dominant families excelled in all conditions, but subordinates performed well in the split condition only, regardless of learning history. Subordinate animals had learned the associations, but expressed their knowledge only when segregated from higher-ranking animals. Because aggressive behavior was rare, performance deficits probably reflected voluntary inhibition. This experimental evidence of rank-related, social modulation of performance calls for greater consideration of social factors when assessing learning and may also have relevance for the evaluation of human scholastic achievement.
