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.

Hybridization Processes: The case of the urban game: Hybrid Hunt: Petrified

The proposal highlights certain design strategies and a case study that can link the material urban space to digital emerging realms. The composite nature of urban spaces ?material/ digital- is understood as an opportunity to reconfigure public urban spaces without high-cost, difficult to apply interventions and, furthermore, to reactivate them by inserting dynamic, interactive and playful conditions that engage people and re-establish their relations to the cities. The structuring of coexisting and interconnected material and digital aspects in public urban spaces is proposed through the implementation of hybridization processes. Hybrid spaces can fascinate and provoke the public and especially younger people to get involved and interact with physical aspects of urban public spaces as well as digital representations or interpretations of those. Digital game?s design in urban public spaces can be comprehended as a tool that allows architects to understand and to configure hybrids of material and digital conceptions and project all in one, as an inseparable totality. Digital technologies have for a long time now intervened in our perception of traditional dipoles such as subject - environment. Architects, especially in the past, have been responsible for material mediations and tangible interfaces that permit subjects to relate to their physical environments in a controlled and regulated manner; but, nowadays, architects are compelled to embody in design, the transition that is happening in all aspects of everyday life, that is, from material to digital realities. In addition, the disjunctive relation of material and digital realms is ceding and architects are now faced with the challenge that supposes the merging of both in a single, all-inclusive reality. The case study is a design project for a game implemented simultaneously in a specific urban space and on the internet. This project developed as the spring semester course New Media in Architecture at the Department of Architecture, Democritus University of Thrace, Greece is situated at the city of Xanthi. Composite cities can use design strategies and technological tools to configure augmented and appealing urban spaces that articulate and connect different realms in a single engaging reality.

Assessment methodology to make urban transport interchanges attractive for users

En las ciudades europeas, los patrones de movilidad son cada vez más complejos debido fundamentalmente a un crecimiento sostenido de la población así como a la tendencia de dispersión de los núcleos urbanos. En consecuencia, muchos de los usuarios del transporte público se ven obligados a combinar varios modos o servicios de transporte para completar sus viajes diarios. Por tanto, el mayor reto de las ciudades es conseguir una mejora e incremento en la movilidad mientras que al mismo tiempo se reducen problemas como la congestión, los accidentes y la contaminación (COM, 2006). Un principio básico para lograr una movilidad sostenible es reducir los inconvenientes y molestias derivados de la transferencia o ruptura del viaje. En este sentido, los intercambiadores de transporte público juegan un papel fundamental como nodos de la red urbana de transporte y la calidad del servicio prestado en ellos tiene una influencia directa sobre la experiencia diaria de los viajeros. Como señaló Terzis and Last (2002), un intercambiador de transportes urbano eficiente debe ser competitivo y al mismo tiempo, debe ser atractivo para los usuarios dado que sus experiencias físicas y sus reacciones psicológicas se ven influenciadas de manera significativa por el diseño y operación del intercambiador. Sin embargo, todavía no existen standards o normativas a nivel europeo que especifiquen como deberían ser estos intercambiadores. Esta tesis doctoral proporciona conocimientos y herramientas de análisis dirigidas a planificadores y gestores de los propios intercambiadores con el fin de entender mejor el funcionamiento de los intercambiadores y gestionar así los recursos disponibles. Así mismo, esta tesis identifica los factores clave en el diseño y operación de intercambiadores urbanos de transporte y proporciona algunas guías generales de planificación en base a ellos. Dado que las percepciones de los usuarios son particularmente importantes para definir políticas adecuadas para intercambiadores, se diseñó y se llevó a cabo en 2013 una encuesta de satisfacción al viajero en tres intercambiadores de transporte urbano europeos: Moncloa (Madrid, España), Kamppi (Helsinki, Finlandia) e Ilford Railway Station ( Londres, Reino Unido). En resumen, esta tesis pone de relieve la naturaleza ambivalente de los intercambiadores urbanos de transporte, es decir, como nodos de la red de transporte y como lugares en sí mismos donde los usuarios pasan tiempo dentro de ellos y propone algunas recomendaciones para hacer más atractivos los intercambiadores a los usuarios. Travel patterns in European urban areas are becoming increasingly complex due to a sustained increase in the urban population and the trend towards urban sprawl. Consequently, many public transport users need to combine several modes or transport services to complete their daily trips. Therefore, the challenge facing all major cities is how to increase mobility while at the same time reducing congestion, accididents and pollution (COM, 2006). Reducing the inconvenience inherent in transferring between modes is a basic principle for achieving sustainable mobility. In this regard, transport interchanges play a key role as urban transport network nodes, and the quality of the service provided in them has a direct influence on travellers' daily experience. As noted by Terzis and Last (2000), an efficient urban transport interchange must be competitive and, at the same time, be attractive for users given that their physical experiences and psychological reactions are significantly influenced by the design and operation of the interchange. However, yet there are no standards or regulations specifying the form these interchanges should take in Europe. This doctoral thesis provides knowledge and analysis tools addressed to developers and managers in order to understand better the performance of an urban transport interchange and manage the available resources properly. Likewise, key factors of the design and operation of urban transport interchanges are identified and some 'Planning guidelines' are proposed on the basis on them. Since the users' perceptions of their experience are particularly important for achieving the most appropriate policy measures for interchanges, an ad‐hoc travellers' satisfaction survey was designed and carried out in 2013 at three European transport interchanges: Moncloa (Madrid, Spain), Kamppi (Helsinki, Finland) and Ilford Railway Station (London, United Kingdom) In summary, this thesis highlights the ambivalent nature of the urban transport interchanges, i.e. as nodes within the transport network and as places where users spending time and proposes some policy recommendations in order to make urban transport interchanges attractive for users.

A Molecular Network That Produces Spontaneous Oscillations in Excitable Cells of Dictyostelium

A network of interacting proteins has been found that can account for the spontaneous oscillations in adenylyl cyclase activity that are observed in homogenous populations of Dictyostelium cells 4 h after the initiation of development. Previous biochemical assays have shown that when extracellular adenosine 3′,5′-cyclic monophosphate (cAMP) binds to the surface receptor CAR1, adenylyl cyclase and the MAP kinase ERK2 are transiently activated. A rise in the internal concentration of cAMP activates protein kinase A such that it inhibits ERK2 and leads to a loss-of-ligand binding by CAR1. ERK2 phosphorylates the cAMP phosphodiesterase REG A that reduces the internal concentration of cAMP. A secreted phosphodiesterase reduces external cAMP concentrations between pulses. Numerical solutions to a series of nonlinear differential equations describing these activities faithfully account for the observed periodic changes in cAMP. The activity of each of the components is necessary for the network to generate oscillatory behavior; however, the model is robust in that 25-fold changes in the kinetic constants linking the activities have only minor effects on the predicted frequency. Moreover, constant high levels of external cAMP lead to attenuation, whereas a brief pulse of cAMP can advance or delay the phase such that interacting cells become entrained.

Sensoriamento automático e participativo em cidades.

As cidades estão a seu tempo e a seu modo, modernizando os serviços prestados à população. Entre os diversos fatores que estão contribuindo para esta evolução estão a diversificação e proliferação de sensores, nos diversos domínios de serviços das cidades, e os novos canais de comunicação com os munícipes, entre eles, as redes sociais e mais recentemente os sistemas crowdsensing, motivados pelos anseios sociais, por melhores serviços públicos e pela popularização dos dispositivos móveis. Nesta direção, a eficiência administrativa é um fator essencial, uma vez que as cidades estão se mostrando mais complexas na medida em que cresce a população nas áreas urbanas. A utilização de técnicas de sistemas distribuídos para que múltiplos domínios de serviços usufruam da mesma infraestrutura computacional, pode auxiliar na eficiência das cidades, evitando gastos administrativos duplicados e até mesmo, possibilitando a correlação de eventos entre os serviços, favorecendo a identificação de fatores de causalidades e assim, a tomada de decisões administrativas mais objetivas e precisas. Neste contexto, este trabalho concentra-se na análise de um middleware direcionado à gestão de cidades para coleta, integração e interpretação dos dados de sensores, pertencentes aos serviços disponíveis da própria cidade, junto com os dados do sensoriamento colaborado pelos cidadãos. Para avaliação do conceito foi investigado o cenário de monitoração da conservação de vias públicas. Após 3 meses de coletas de dados por um sistema de sensoriamento automático, totalizando mais de 360 mil pontos e também mais de 90 relatórios pelo sensoriamento participativo, verificou-se que um sistema distribuído pode realizar a interpretação de séries históricas, engajar os munícipes apoiar a manutenção dos serviços da cidade e também indicar objetivamente aos gestores públicos os pontos que devem ser prioritariamente atendidos. Aliar ferramentas pelas quais o cidadão pode, de acordo com sua necessidade, convicção e altruísmo, exercer influência nos gestores públicos com o suporte de informação contínua e critérios objetivos das redes de sensores, pode estimular a continua excelência dos serviços públicos.

Don’t Let Me Down: An Autoethnography of an Urban Teacher

Students in urban schools who are negatively impacted need stability and continuity the most. However, at least half of new teachers leave their profession within five years. In order for this situation to change, support is needed for new teachers and encouragement is needed for experienced teachers. The purpose of the study is to offer a first-hand description of factors that affect the profession of teaching and especially teachers who may be wondering how to stay in teaching for more than five years. Veteran teachers gain the opportunity to reflect, validate, and (probably) celebrate their own journey through this profession. This autoethnography uses my experience of a 29-year veteran teacher, who started with an alternative teaching license, to mirror what researchers have identified as key factors for sustainability and how they affected my continued commitment to teaching in urban schools. The following questions framed the study: 1. Why did I choose teaching as a career? 2. What supportive factors contributed to my decision to continue teaching in an urban school rather than leave the profession? 3. What internal and external struggles have I encountered in teaching and what strategies did I use to overcome them? 4. What beliefs and experiences led to my steadfast commitment to teaching in an urban setting? 5. How do I define success as an urban teacher? 6. What are the implications of my story for urban education? This autoethnography involves data collection and in-depth analysis of documents and artifacts that were generated during my teaching career as an urban educator. These documents and artifacts come from both internal and external sources. The study’s implications reach beyond teachers and include two sub-groups: teacher education programs and school administrators. The implication for teachers is the importance of a two-fold support system in order to thrive: first teachers need spiritual support and second they need to surround themselves with likeminded teachers. The implications for teacher education programs include making pre-service teachers aware of the realities of urban settings and provide them with resources, which could help overcome the attrition rate. Additionally, pre-service teachers need to know how to form credible relationships with their students. This study also reveals the important role that school principals play in the success of their teachers. First, principals are responsible for creating a positive school climate that promotes a professional learning community. Second, they need to establish relational trust in their building. Third, they need to nourish their staff both physically and emotionally. Finally, the implications of autoethnography for teachers and researchers are also discussed.

Impedance spectroscopy study of the effect of environmental conditions in the microstructure development of OPC and slag cement mortars

In this work, the microstructure of mortars made with an ordinary Portland cement and slag cement has been studied. These mortars were exposed to four different constant temperature and relative humidity environments during a 180-day period. The microstructure has been studied using impedance spectroscopy, and mercury intrusion porosimetry as a contrast technique. The impedance spectroscopy parameters make it possible to analyze the evolution of the solid fraction formation for the studied mortars and their results are confirmed with those obtained using mercury intrusion porosimetry. The development of the pore network of mortars is affected by the environment. However, slag cement mortars are more influenced by temperature while the relative humidity has a greater influence on the OPC mortars. The results show that slag cement mortars hardened under non-optimal environments have a more refined microstructure than OPC mortars for the studied environmental conditions.

Urban environmental degradation and the standard of living: the case of the Spanish mining industry (1870–1930)

This paper analyses the consequences of urban environmental degradation on the well-being of Spanish miners. It is based on analyses of differences in mortality and height. The first part of the paper examines new hypotheses regarding the urban penalty. We take into consideration existing works in economic theory that address market failures when analysing the higher urban death rate. We explain the reduction in height using the model recently created by Floud, Fogel, Harris and Hong for British cities. The second part of the paper presents information demonstrating that the urban areas in the two largest mining areas in Spain (Bilbao and the Cartagena-La Unión mountain range) experienced a higher death rate relative to rural areas as a consequence of market failures derived from what we term an ‘anarchic urbanisation’.

Differences and connections: beyond universal theories in planning, urban, and heritage studies

The annual Young Academics network of the Association of European School of Planning (AESOP YA) conference, entitled Differences and Connections, was held for the first time in a Southern Italian city, Palermo, Italy, during 23–26 March 2015. The call for papers attracted a wide range of authors within the field of planning and other related fields. Forty-five contributions by young academic scholars, representing 19 countries, were selected by the conference scientific committee to critically explore the themes of the conference.

Comparison of rural and urban attitudes to the conservation of Asian elephants in Sri Lanka: empirical evidence

There has been little study of economic and general attitudes towards the conservation of the Asian elephant. This paper reports and analyses results from surveys conducted in Sri Lanka of attitudes of urban dwellers and farmers towards nature conservation in general and the elephant conservation in particular. The analyses are based on urban and a rural sample. Contingent valuation techniques are used as survey instruments. Multivariate logit regression analysis is used to analyse the respondents' attitudes towards conservation of elephants. It is found that, although some variations occurred between the samples, the majority of the respondents (both rural and urban) have positive attitudes towards nature conservation in general. However, marked differences in attitudes toward elephant conservation are evident between these two samples: the majority of urban respondents were in favour of elephant conservation; rural respondents expressed a mixture of positive and negative attitudes. Overall, considerable unrecorded and as yet unutilised economic support for conservation of wild elephants exists in Sri Lanka. (C) 2002 Elsevier Science Ltd. All rights reserved.

The prevalence of childhood obesity in primary school children in urban Khon Kaen, Northeast Thailand

Childhood obesity is a serious public health problem because of its strong association with adulthood obesity and the related adverse health consequences. The published literature indicates a rising prevalence of childhood obesity in both developed and developing countries. However no data exists on the prevalence in Northeast Thailand, one of the poorest regions of the country and one that has experienced a recent economic transition. The objective of this study was to estimate the prevalence of obesity in seven to nine year old children in urban Khon Kaen, Northeast Thailand. A cross-sectional school based survey was conducted to determine the prevalence of obesity in children of urban Khon Kaen, Thailand. Multi-staged cluster sampling was used to select 12 school clusters of 72 children each between the ages of 7 and 9 years, in primary school grades 1, 2 and 3 from government, private and demonstration schools. A total of 864 seven to nine year old school children were studied. Anthropometric measurements of standing height and weight were taken for all subjects to the nearest tenth of a centimetre and tenth of a kilogram respectively. Childhood obesity was defined as a weight-for-height Z-score above 2.0 standard deviations of the National Center for Health Statistics/World Health Organisation reference population median. The prevalence of childhood obesity was 10.8% (95% CI: 7.6, 13.9). Obesity was significantly more prevalent in boys than girls. The biggest difference was observed between the three school types, with the highest prevalence of obesity found at teacher training demonstration schools and the lowest at the government schools. This study provides the first data on childhood obesity prevalence in Northeast Thailand. The prevalence of 10.8 per cent is lower than that found in two other urban areas of Thailand but slightly higher than expected for this relatively poor region. If this prevalence rate increases, as observed in other countries in economic transition, the incidence of non-communicable diseases associated with obesity is also likely to increase, thus raising cause for concern and reason for intervention to both control and prevent obesity during childhood.

Review of the ecology of Australian urban fauna: A focus on spatially explicit processes

Cities have a major impact on Australian landscapes, especially in coastal regions, to the detriment of native biodiversity. Areas suitable for urban development often coincide with those areas that support high levels of species diversity and endemism. However, there is a paucity of reliable information available to guide urban conservation planning and management, especially regarding the trade-off between investing in protecting and restoring habitat at the landscape level, and investing in programmes to maintain the condition of remnant vegetation at the local (site) level. We review the literature on Australian urban ecology, focusing on urban terrestrial and aquatic vertebrate and invertebrate fauna. We identify four main factors limiting our knowledge of urban fauna: (i) a lack of studies focusing at multiple ecological levels; (ii) a lack of multispecies studies; (iii) an almost total absence of long-term (temporal) studies; and (iv) a need for stronger integration of research outcomes into urban conservation planning and management. We present a set of key principles for the development of a spatially explicit, long-term approach to urban fauna research. This requires an understanding of the importance of local-level habitat quality and condition relative to the composition, configuration and connectivity of habitats within the larger urban landscape. These principles will ultimately strengthen urban fauna management and conservation planning by enabling us to prioritize and allocate limited financial resources to maximize the conservation return.
