Análisis de la dinámica inmobiliaria y comportamiento del precio del suelo en la UPZ nº 13 Los Cedros 2000 - 2012

El presente estudio de caso tiene como propósito analizar la relación entre la dinámica inmobiliaria y el comportamiento del precio del suelo en la UPZ N° 13 Los Cedros entre los años 2000 y 2012. Esta investigación parte de la importancia de entender y explicar las causas generales, coyunturales y particulares por las que el precio del suelo en las ciudades es cambiante y hace que exista una dinámica inmobiliaria encargada de gestionar el mercado de tierras en un determinado sector, llevándolo a una transformación urbanística. Por último, se analiza cómo dos intervenciones comerciales influyen en el comportamiento del precio del suelo, con la finalidad de identificar qué efectos positivos o negativos producen en la zona aledaña a ellas.

Informe final creación y evaluación de campo de un instrumento para la medición de las competencias clínicas en Fisioterapia

La evaluación de los procesos formativos en el área clínica, basados en competencias, es fundamental para la Fisioterapia. Este proceso articula la teoría con la práctica, orienta la organización de los procesos académicos, promueve la formación integral y establece mecanismos de retroalimentación permanentes y rigurosos, basados en la evaluación del desempeño del profesional en formación ante situaciones del día a día que dan cuenta de su toma de decisiones profesional. Se espera que los estudiantes se formen y puedan actuar como profesionales competitivos a nivel nacional e internacional, de manera integral, con sólidos compromisos éticos y sociales para responder a las necesidades del entorno social en el que se desenvuelven (PEP, Universidad del Rosario). Los esfuerzos actuales en investigación de la evaluación educativa se encuentran orientados a la integración de la adquisición del conocimiento y al desarrollo de estrategias de medición y cuantificación de capacidades técnico-científicas dentro de cada disciplina. En este sentido, hasta el momento, en Colombia no se encuentra evidencia alrededor de la validación de instrumentos de medición de las competencias clínicas, ni se cuenta con estándares para la evaluación en práctica clínica en el proceso de formación del recurso humano en Fisioterapia. En el proyecto se desarrolló y fueron evaluadas las propiedades psicométricas de un instrumento que mide las competencias clínicas del estudiante de fisioterapia en la práctica clínica. Este proceso involucró a Fisioterapeutas que con experiencia en el área de docencia y clínica, contribuyen con la formación de fisioterapeutas en Colombia.

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

Supervisory systems in waste water treatment plants: sistematise their implementation

La implantació de Sistemes de Suport a la presa de Decisions (SSD) en Estacions Depuradores d'Aigües Residuals Urbanes (EDAR) facilita l'aplicació de tècniques més eficients basades en el coneixement per a la gestió del procés, assegurant la qualitat de l'aigua de sortida tot minimitzant el cost ambiental de la seva explotació. Els sistemes basats en el coneixement es caracteritzen per la seva capacitat de treballar amb dominis molt poc estructurats, i gran part de la informació rellevant de tipus qualitatiu i/o incerta. Precisament aquests són els trets característics que es poden trobar en els sistemes biològics de depuració, i en conseqüència en una EDAR. No obstant, l'elevada complexitat dels SSD fa molt costós el seu disseny, desenvolupament i aplicació en planta real, pel que resulta determinant la generació d'un protocol que faciliti la seva exportació a EDARs de tecnologia similar. L'objectiu del present treball de Tesi és precisament el desenvolupament d'un protocol que faciliti l'exportació sistemàtica de SSD i l'aprofitament del coneixement del procés prèviament adquirit. El treball es desenvolupa en base al cas d'estudi resultant de l'exportació a l'EDAR Montornès del prototipus original de SSD implementat a l'EDAR Granollers. Aquest SSD integra dos tipus de sistemes basats en el coneixement, concretament els sistemes basats en regles (els quals són programes informàtics que emulen el raonament humà i la seva capacitat de solucionar problemes utilitzant les mateixes fonts d'informació) i els sistemes de raonament basats en casos (els quals són programes informàtics basats en el coneixement que volen solucionar les situacions anormals que pateix la planta en el moment actual mitjançant el record de l'acció efectuada en una situació passada similar). El treball està estructurat en diferents capítols, en el primer dels quals, el lector s'introdueix en el món dels sistemes de suport a la decisió i en el domini de la depuració d'aigües. Seguidament es fixen els objectius i es descriuen els materials i mètodes utilitzats. A continuació es presenta el prototipus de SSD desenvolupat per la EDAR Granollers. Una vegada el prototipus ha estat presentat es descriu el primer protocol plantejat pel mateix autor de la Tesi en el seu Treball de Recerca. A continuació es presenten els resultats obtinguts en l'aplicació pràctica del protocol per generar un nou SSD, per una planta depuradora diferent, partint del prototipus. L'aplicació pràctica del protocol permet l'evolució del mateix cap a un millor pla d'exportació. Finalment, es pot concloure que el nou protocol redueix el temps necessari per realitzar el procés d'exportació, tot i que el nombre de passos necessaris ha augmentat, la qual cosa significa que el nou protocol és més sistemàtic.

Management of industrial wastewater discharges in river basins through agents'argumentation

La gestió de l'aigua residual és una tasca complexa. Hi ha moltes substàncies contaminants conegudes però encara moltes per conèixer, i el seu efecte individual o col·lgectiu és difícil de predir. La identificació i avaluació dels impactes ambientals resultants de la interacció entre els sistemes naturals i socials és un assumpte multicriteri. Els gestors ambientals necessiten eines de suport pels seus diagnòstics per tal de solucionar problemes ambientals. Les contribucions d'aquest treball de recerca són dobles: primer, proposar l'ús d'un enfoc basat en la modelització amb agents per tal de conceptualitzar i integrar tots els elements que estan directament o indirectament involucrats en la gestió de l'aigua residual. Segon, proposar un marc basat en l'argumentació amb l'objectiu de permetre als agents raonar efectivament. La tesi conté alguns exemples reals per tal de mostrar com un marc basat amb agents que argumenten pot suportar diferents interessos i diferents perspectives. Conseqüentment, pot ajudar a construir un diàleg més informat i efectiu i per tant descriure millor les interaccions entre els agents. En aquest document es descriu primer el context estudiat, escalant el problema global de la gestió de la conca fluvial a la gestiódel sistema urbà d'aigües residuals, concretament l'escenari dels abocaments industrials. A continuació, s'analitza el sistema mitjançant la descripció d'agents que interaccionen. Finalment, es descriuen alguns prototips capaços de raonar i deliberar, basats en la lògica no monòtona i en un llenguatge declaratiu (answer set programming). És important remarcar que aquesta tesi enllaça dues disciplines: l'enginyeria ambiental (concretament l'àrea de la gestió de les aigües residuals) i les ciències de la computació (concretament l'àrea de la intel·ligència artificial), contribuint així a la multidisciplinarietat requerida per fer front al problema estudiat. L'enginyeria ambiental ens proporciona el coneixement del domini mentre que les ciències de la computació ens permeten estructurar i especificar aquest coneixement.

Construção de uma nova profissionalidade docente das equipas pedagógicas dos cursos de educação e formação através da sua transformação em comunidades de aprendizagem profissional

O sistema educativo e formativo português tem vindo a mudar significativamente, devido ao fenómeno da globalização e às exigências da sociedade do conhecimento. Com efeito, os desafios de uma economia mais dinâmica e competitiva, baseada no conhecimento requerem a definição de novas políticas educativas. Os objetivos de aumentar a equidade e a oportunidade de educação para todos os alunos e de combater o abandono e o insucesso escolar conduziram à implementação, em Portugal, de algumas medidas que envolvam os jovens em programas de formação, tais como os cursos de educação e formação (CEF). É no seio deste novo e complexo contexto educativo que colocamos a relevante questão: como podem as equipas pedagógicas dos cursos de educação e formação responder, adequadamente, às exigências de atuação neste tipo de percurso diversificado de formação? A natureza dos constantes constrangimentos que os professores enfrentam permitiu-nos concluir que estes têm de trabalhar sobre a sua própria capacidade de mudança, de forma a responderem a todas estas crescentes demandas, pelo que, neste sentido, a mudança assume-se como uma extraordinária oportunidade de desenvolvimento profissional. Esta construção de capacidade ou reculturing (Fullan, 2007) é o resultado de várias adaptações e decisões, tomadas pelos professores, colaborativamente como comunidades de aprendizagem profissional (CAP). Na verdade, nas CAP os docentes estão moral e intelectualmente comprometidos com a melhoria, a inovação e a sustentabilidade da educação, por conseguinte elas não são apenas um meio de melhorar os resultados dos alunos e de aumentar as suas aprendizagens, como são, também, o processo mais eficaz de implicar os docentes no desenvolvimento profissional contínuo, profundamente ligado à ação. Consequentemente, no sentido de transformar as equipas pedagógicas em comunidades de aprendizagem profissional apresentamos um projeto de formação que se concretizará através da implementação de um círculo de estudos, no contexto escolar, que pretende assegurar o desenvolvimento e a atualização dos conhecimentos e competências dos professores dos CEF e melhorar a qualidade e eficácia da aprendizagem e da prática docente. As expectativas em relação aos resultados desta formação são bastante elevadas e alicerçam-se na recetividade e disponibilidade demonstradas, por todos os professores dos CEF, para participarem neste projeto de formação.

Utilização de modelos farmacocinéticos de base fisiológica no desenvolvimento de novos fármacos

Nas últimas décadas tem-se verificado um aumento bastante acentuado da utilização de modelos in vitro e in silico para a obtenção de dados que permitem aumentar a eficácia de programas de desenvolvimento de novos fármacos. Actualmente são utilizados dois tipos de modelos para descrever a farmacocinética de compostos químicos em função do tempo: modelos empíricos farmacocinéticos e modelos farmacocinéticos baseados na fisiologia (PBPK). Modelos PBPK assumem que o corpo humano interage com os compostos químicos como um sistema integrado, pelo que um evento que ocorre numa zona do corpo poderá influenciar um evento a ocorrer noutra zona, aparentemente distinta. Estes modelos assumem que o organismo humano é constituído por “compartimentos” que representam fisiologicamente os órgãos, tecidos e outros espaços fisiológicos. Para a correcta utilização destes modelos é necessário determinar a estrutura do modelo e as suas características, escrever equações que o caracterizem, bem como definir e estimar os parâmetros deste. Estes modelos têm vindo a ser usados no campo toxicológico e farmacêutico cada vez com maior frequência. No futuro poder-se-ão transformar numa ferramenta universal.

Managing land-use conflict around urban centres: Australian poultry farmer attitudes towards relocation

In analysing the release of agricultural land to urban development, the urban fringe literature has not focused on whether farmers are able to relocate from the urban fringe to remoter rural areas. Through interviews with representatives from the poultry industry in two Australian states, this paper identifies that poultry farm relocation strategies are constrained by off-farm economic relations, the land-use planning system and financial considerations. Closely aligned to these constraints on relocation is the on-going process of poultry farm intensification, which is seen as presenting rising problems for land-use management around expanding metropolitan centres in Australia. Of particular concern is the potential for amenity complaints and associated land-use conflicts, which have not been comprehensively investigated. Recognising that existing environmental and land-use planning controls are ineffective in producing amicable solutions when conflict involving poultry farming is at its most intense, the paper calls for improvements to the regulatory system, including greater consideration for how the process of relocation can be encouraged.

Urban mammals: what does the future hold? An analysis of the factors affecting patterns of use of residential gardens in Great Britain

1Urban areas are predicted to grow significantly in the foreseeable future because of increasing human population growth. Predicting the impact of urban development and expansion on mammal populations is of considerable interest due to possible effects on biodiversity and human-wildlife conflict. 2The British government has recently announced a substantial housing programme to meet the demands of its growing population and changing socio-economic profile. This is likely to result in the construction of high-density, low-cost housing with small residential gardens. To assess the potential effects of this programme, we analysed the factors affecting the current pattern of use of residential gardens by a range of mammal species using a questionnaire distributed in wildlife and gardening magazines and via The Mammal Society. 3Twenty-two species/species groups were recorded. However, the pattern of garden use by individual species was limited, with only six species/species groups (bats, red fox Vulpes vulpes, grey squirrel Sciurus carolinensis, hedgehog Erinaceus europaeus, mice, voles) recorded as frequent visitors to > 20% of gardens in the survey. 4There was a high degree of association between the variables recorded in the study, such that it was difficult to quantify the effects of individual variables. However, all species/species groups appeared to be negatively affected by the increased fragmentation and reduced proximity of natural and semi-natural habitats, decreasing garden size and garden structure, but to differing degrees. Patterns of garden use were most clearly affected by house location (city, town, village, rural), with garden use declining with increasing urbanization for the majority of species/species groups, except red foxes and grey squirrels. Increasing urbanization is likely to be related to a wide range of interrelated factors, any or all of which may affect a range of mammal species. 5Overall, the probable effects of the planned housing development programme in Britain are not likely to be beneficial to mammal populations, although the pattern of use examined in this study may represent patterns of habitat selection by species rather than differences in distribution or abundance. Consequently, additional data are required on the factors affecting the density of species within urban environments.

High throughput profile-profile based fold recognition for the entire human proteome

BACKGROUND: In order to maintain the most comprehensive structural annotation databases we must carry out regular updates for each proteome using the latest profile-profile fold recognition methods. The ability to carry out these updates on demand is necessary to keep pace with the regular updates of sequence and structure databases. Providing the highest quality structural models requires the most intensive profile-profile fold recognition methods running with the very latest available sequence databases and fold libraries. However, running these methods on such a regular basis for every sequenced proteome requires large amounts of processing power.In this paper we describe and benchmark the JYDE (Job Yield Distribution Environment) system, which is a meta-scheduler designed to work above cluster schedulers, such as Sun Grid Engine (SGE) or Condor. We demonstrate the ability of JYDE to distribute the load of genomic-scale fold recognition across multiple independent Grid domains. We use the most recent profile-profile version of our mGenTHREADER software in order to annotate the latest version of the Human proteome against the latest sequence and structure databases in as short a time as possible. RESULTS: We show that our JYDE system is able to scale to large numbers of intensive fold recognition jobs running across several independent computer clusters. Using our JYDE system we have been able to annotate 99.9% of the protein sequences within the Human proteome in less than 24 hours, by harnessing over 500 CPUs from 3 independent Grid domains. CONCLUSION: This study clearly demonstrates the feasibility of carrying out on demand high quality structural annotations for the proteomes of major eukaryotic organisms. Specifically, we have shown that it is now possible to provide complete regular updates of profile-profile based fold recognition models for entire eukaryotic proteomes, through the use of Grid middleware such as JYDE.

Understanding construction consortia: Theory, practice and opinions

Firms form consortia in order to win contracts. Once a project has been awarded to a consortium each member then concentrates on his or her own contract with the client. Therefore, consortia are marketing devices, which present the impression of teamworking, but the production process is just as fragmented as under conventional procurement methods. In this way, the consortium forms a barrier between the client and the actual construction production process. Firms form consortia, not as a simple development of normal ways of working, but because the circumstances for specific projects make it a necessary vehicle. These circumstances include projects that are too large or too complex to undertake alone or projects that require on-going services which cannot be provided by the individual firms inhouse. It is not a preferred way of working, because participants carry extra risk in the form of liability for the actions of their partners in the consortium. The behaviour of members of consortia is determined by their relative power, based on several factors, including financial commitment and ease of replacement. The level of supply chain visibility to the public sector client and to the industry is reduced by the existence of a consortium because the consortium forms an additional obstacle between the client and the firms undertaking the actual construction work. Supply chain visibility matters to the client who otherwise loses control over the process of construction or service provision, while remaining accountable for cost overruns. To overcome this separation there is a convincing argument in favour of adopting the approach put forward in the Project Partnering Contract 2000 (PPC2000) Agreement. Members of consortia do not necessarily go on to work in the same consortia again because members need to respond flexibly to opportunities as and when they arise. Decision-making processes within consortia tend to be on an ad hoc basis. Construction risk is taken by the contractor and the construction supply chain but the reputational risk is carried by all the firms associated with a consortium. There is a wide variation in the manner that consortia are formed, determined by the individual circumstances of each project; its requirements, size and complexity, and the attitude of individual project leaders. However, there are a number of close working relationships based on generic models of consortia-like arrangements for the purpose of building production, such as the Housing Corporation Guidance Notes and the PPC2000.

Role of knowledge in managing construction change

Purpose-Unplanned changes in construction projects are common and lead to disruptive effects such as project delays, cost overruns and quality deviations. Rework due to unplanned changes can cost 10-15 per cent of contract value. By managing these changes more effectively, these disruptive effects can be minimised. Previous research has approached this problem from an information-processing view. In this knowledge age, the purpose of this paper is to argue that effective change management can be brought about by better understanding the significant role of knowledge during change situations. Design/methodology/approach - Within this knowledge-based context, the question of how construction project teams manage knowledge during unplanned change in the construction phase within collaborative team settings is investigated through a selected case study sample within the UK construction industry. Findings- Case study findings conclude that different forms of knowledge are created and shared between project team members during change events which is very much socially constructed and centred on tacit knowledge and experience of project personnel. Originality/value- Building on the case study findings the paper finally offers a model that represents the role of knowledge during managing project change.

Modelling: promoting creativity whilst forging links between science education and design and technology education

Educational reforms in many countries currently call for the development of knowledge-based societies. In particular, emphasis is placed on the promotion of creativity, especially in the areas of science education and of design and technology education. In this paper, perceptions of the nature of creativity and of the conditions for its realization are discussed. The notion of modelling as a creative act is outlined and the scope for using modelling as a bridge between science education and design and technology education explored. A model for the creative act of modelling is proposed and its major aspects elaborated upon. Finally, strategies for forging links between the two subjects are outlined.
