O legado das colonizações da Amazônia oriental: redes de aglomerados rurais ou redes proto-urbanas?
Authors: Pinho Giselle Fernandes de , Cardoso Ana Cláudia Duarte
Published: September 2016

Este artigo assume estudos de caso nos Municípios de Moju e Acará para investigar uma rede de pequenas aglomerações que compõem o território rural do nordeste paraense. Normalmente invisível aos órgãos oficiais e não considerada no desenho das políticas públicas rurais e urbanas, esses aglomerados efetivamente estruturam o território rural, como pode ser apreendido por meio de cartografia social. O objetivo deste artigo é relacionar os níveis hierárquicos dessa rede de aglomerados rurais aos resquícios das políticas colonizadoras. A metodologia utilizada foi qualitativa voltada para a análise de padrões sócio-espaciais, utilizando como ferramentas a cartografia social e a teoria dos grafos para gerar um gradiente urbano-rural e os níveis de hierarquia da rede. Apesar da prevalência de funções agrárias, assumidas como ponto de partida da colonização realizada nos anos 1970, observa-se a disseminação de aglomerados rurais hierarquizados por centralidade, disponibilidade de serviços, estratégias de subsistência e coesão social, que articulam usos rurais a expectativas de consumo e acesso às políticas públicas normalmente associadas ao universo urbano, conectando esses dois mundos. O resultado de tantas superposições é um território híbrido cuja morfologia e padrão socioespacial em rede são pouco compreendidos e valorizados tanto pelo setor público quanto pela iniciativa privada.

Authors:   Associate Professor, Dept of ECE, VVCE, Mysore, M Patil , Mr. Chandrashekar ,   Associate Professor, Dept of ECE, VVCE, Mysore
Published: September 2016

Diabetic Retinopathy is a common complication of diabetes that is caused by changes in the blood vessels of the retina. The blood vessels in the retina get altered. Exudates are secreted, micro-aneurysms and hemorrhages occur in the retina. The appearance of these features represents the degree of severity of the disease. In this paper the proposed approach detects the presence of abnormalities in the retina using image processing techniques by applying morphological processing techniques to the fundus images to extract features such as blood vessels, micro aneurysms and exudates. These features are used for the detection of severity of Diabetic Retinopathy. It can quickly process a large number of fundus images obtained from mass screening to help reduce the cost, increase productivity and efficiency for ophthalmologists.

The ever-increasing availability of textual documents has lead to a growing challenge for information systems to effectively manage and retrieve the information comprised in large collections of texts according to the user�s information needs. There is no clustering method that can adequately handle all sorts of cluster structures and properties (e.g. shape, size, overlapping, and density). Combining multiple clustering methods is an approach to overcome the deficiency of single algorithms and further enhance their performances. A disadvantage of the cluster ensemble is the highly computational load of combing the clustering results especially for large and high dimensional datasets. In this paper we propose a multiclustering algorithm , it is a combination of Cooperative Hard-Fuzzy Clustering model based on intermediate cooperation between the hard k-means (KM) and fuzzy c-means (FCM) to produce better intermediate clusters and ant colony algorithm. This proposed method gives better result than individual clusters.

Certain Investigation on Dynamic Clustering in Dynamic Datamining
Authors:   Associate Professor, CSE Department, Karpagam college of Engineering,Coimbatore, India, Mary S.Angel Latha
Published: September 2016

Clustering is the process of grouping a set of objects into classes of similar objects. Dynamic clustering comes in a new research area that is concerned about dataset with dynamic aspects. It requires updates of the clusters whenever new data records are added to the dataset and may result in a change of clustering over time. When there is a continuous update and huge amount of dynamic data, rescan the database is not possible in static data mining. But this is possible in Dynamic data mining process. This dynamic data mining occurs when the derived information is present for the purpose of analysis and the environment is dynamic, i.e. many updates occur. Since this has now been established by most researchers and they will move into solving some of the problems and the research is to concentrate on solving the problem of using data mining dynamic databases. This paper gives some investigation of existing work done in some papers related with dynamic clustering and incremental data clustering.

The DEMATEL method is then a good technique for making decisions. In this paper we analyzed the risk factors of youth violence and what makes them more aggressive. Since there are more risk factors of youth violence, to relate each other more complex to construct FCM and analyze them. Moreover the data is an unsupervised one obtained from survey as well as interviews. Hence fuzzy alone has the capacity to analyses these concepts.
Creole Hens and Ranga-Ranga: Campesino Foodways and Biocultural Resource-Based Development in the Central Valley of Tarija, Bolivia
Authors: Turner Katherine L. , Davidson-Hunt Iain J. , Desmarais Annette Aurélie , Hudson Ian
Published: September 2016

Biocultural heritage-based products, including regional specialty foods, are increasingly part of sustainable rural development strategies. While export-oriented biocultural products are often the most visible, we examine the role of campesino gastronomic heritage in the Central Valley of Tarija, Bolivia, as a case study of a local market-centered biocultural resource-based development strategy reflected in an alternative agri-food network. We develop a biocultural sustainability framework to examine this network from ecological, economic and sociocultural perspectives. Data are drawn from interviews (n=77), surveys (n=89) and participant observation, with primary and secondary producers of traditional and new products, as well as restaurant owners, market vendors and local consumers. We find that campesino biocultural heritage and the alternative agri-food network surrounding it represent an influential territorial project that underpins many household economies, particularly for women. We conclude that the relatively small investments by local governments to promote campesino gastronomic heritage are having positive ripple effects on small-scale producer livelihoods and on biocultural sustainability. We suggest that further support to increase market access and reduce other barriers to participation in alternative food networks will likely increase the options and benefits available to small-scale producers mobilising campesino gastronomic heritage within the local economy.
Assessment of Impediments and Factors Affecting Waste Management: A Case of Accra Metropolis
Authors: Fagariba Clifford James , Song Shaoxian
Published: September 2016

Solid waste management in Accra is a major challenge to the Metropolitan Authorities and inhabitants. The rapidly increasing population coupled with poor capacity of the municipal and private waste management companies to management waste effectively has created issues of environmental concern. Due to poor waste managements systems, most household dispose waste indiscriminately leading to floods and health issues. The study showed that about 60% of household waste is organic materials which has the potential to be converted to compost for agriculture purpose. Meanwhile plastics and rubbers which litters the environment as well as blocking major storm drains and gutters hence creating huge environmental hazard is made of 11% of the total component of most household waste generated daily. The study also revealed that among the methods of disposing waste, dumping waste in skip containers located at authorized places was the preferred means of disposing waste by household though others also dispose waste by other means such as burying and burning. Inadequate skip containers per population of household in an area coupled with irregularity of tracks picking these containers makes skip containers dumping site ugly scene, hence creating health issues. Among the constraints that impact negatively on sustainable waste management in Accra Metropolis, economic constraints was perceived as the main challenge which affect efficient waste management. Currently the country is going through serious economic challenges so government does not release money timely to fund projects which waste management is key. Most donor partners that use to support the government with funds have either reduced or redrawn their services as they have no confidence in the state of Ghana economy. Aside the constrains, the study also indicated that factors such as poor public attitude towards waste management, poor enforcement of sanitation by-laws, inadequate and untimely release of government funds were also seen as the main factors affecting waste management.
Decision and Coordination of Carbon Emissions Reduction Strategy in a Two-Echelon Supply Chain Considering Vertical Technology Spillovers
Authors: XU Lang , WANG Chuanxu , LI Hui
Published: September 2016

We study a two-echelon supply chain made up of a supplier and a manufacturer, both of which can reduce their component/product carbon emissions. With the vertical technology spillovers, we explore the optimal decisions of centralized and decentralized supply chains with price dependent demand and propose coordination strategy for the decentralized supply chain. Considering the cost contraction effectiveness of the technology spillovers, the centralized and decentralized game theoretic models of a two-echelon supply chain are developed to investigate optimal decisions of pricing and carbon emissions reduction. Through a systematic comparison and numerical analysis, we show that the profits of both players and the entire supply chain improve with the effect of technology spillovers increasing. Carbon emissions reduction will be taken by various protective measures so that the supplier and the manufacturer who do not innovate can hardly share the results of innovating via the “free-riding” methods when the technology spillover is relatively small. We also propose a revenue-cost sharing contract through bargaining to enhance the performance of the decentralized supply chain.
Ensemble Prediction Model with Expert Selection for Electricity Price Forecasting
Authors: Neupane Bijay , Woon Wei Lee , Aung Zeyar
Published: September 2016

Day-ahead forecasting of electricity prices is important in deregulated electricity markets for all the stakeholders: energy wholesalers, traders, retailers, and consumers. Electricity price forecasting is an inherently difficult problem due to its special characteristic of dynamicity and non-stationarity. In this paper, we present a robust price forecasting mechanism that shows resilience towards aggregate demand response effect and provides highly accurate forecasted electricity prices to the stakeholders in a dynamic environment. We employ an ensemble prediction model in which a group of different algorithms participate in predicting the price for each hour of a day. We propose two different strategies, namely, Fixed Weight Method (FWM) and Varying Weight Method (VWM), for selecting each hour's expert algorithm from the set of participating algorithms. In addition, we utilize a carefully engineered set of features selected from a pool of features derived from information such as past electricity price data, weather data, and calendar data. The proposed ensemble model offers better results than both the Pattern Sequence-based Forecasting (PSF) method and our own previous work using Artificial Neural Networks (ANN) alone do on the datasets for New York, Australian, and Spanish electricity markets.
An Inter-Comparison of Techniques for Determining Velocities of Maritime Arctic Glaciers, Svalbard, Using Radarsat-2 Wide Fine Mode Data
Authors: Schellenberger Thomas , Van Wychen Wesley , Copland Luke , Kääb Andreas , Gray Laurence
Published: September 2016

Glacier dynamics play an important role in the mass balance of many glaciers, ice caps and ice sheets. In this study we exploit Radarsat-2 (RS-2) Wide Fine (WF) data to determine the surface speed of Svalbard glaciers in the winters of 2012/2013 and 2013/2014 using Synthetic Aperture RADAR (SAR) offset and speckle tracking. The RS-2 WF mode combines the advantages of the large spatial coverage of the Wide mode (150 x 150 km) and the high pixel resolution (9m) of the Fine mode and thus has a major potential for glacier velocity monitoring from space through offset and speckle tracking. Faster flowing glaciers (1.95 md-1 - 2.55 md-1) which are studied in more detail are Nathorstbreen, Kronebreen, Kongsbreen and Monacobreen. Using our Radarsat-2 Wide Fine dataset, we compare the performance of two SAR tracking algorithms, namely the GAMMA Remote Sensing Software and a custom written MATLAB script that has primarily been used in the Canadian Arctic. Both algorithms provide comparable results, especially for the faster flowing glaciers and the termini of slower tidewater glaciers. A comparison of the WF data to RS-2 Ultrafine and Wide mode data reveals the superiority of RS-2 WF data over the Wide mode data.

➢ Both static and dynamic bracing are effective for increasing elbow range of motion when heterotopic ossification is not present.

➢ Some loss of immediate postoperative range of motion is expected.

➢ Recurrence of heterotopic ossification around the elbow is rare.

➢ The occurrence of ulnar nerve palsy is rare and often requires transposition.
Safety for a Helicopter Load/Unload Operation on an Offshore Platform: Optimization From Several Viewpoints and the Psychological Aspects of the Marshaller
Authors: Yonebayashi Hideharu , Collins Tim
Published: September 2016

When a slickline and/or an electrical wireline job is required on offshore oil/gas platforms that have no crane equipment, a helicopter load/unload operation is a common method used for transporting materials such as winch units, power-pack units, blowout-preventer (BOP) units, and lubricators from the platform or from the offshore complex to the platform. A series of materials is transported separately by helicopter so that one lifted material can be within the maximum loading capacity of the helicopter. A materials-transportation package typically consists of four or five load/unload operations for an entire set of materials. These frequent load/unload operations are performed with a hovering action, which has the highest risk among helicopter actions (i.e., taking off, cruising, and approaching/landing). To achieve safety, all risk-mitigating factors are adequately incorporated into a plan that should be shared with all crew (pilot, company supervisor, slickline/wireline operators) in advance of the operation.

This paper discusses mitigations from various points of view, in addition to summarizing general safety tips. As a result of considering the psychological response of the ground crew on the basis of actual field experience, this paper recommends how to remove mental factors that silently act on the actions of a helicopter marshaller. Moreover, fundamental measures are recommended to update marshalling methods and to use new-generation helicopters that are designed for improved safety requirements.
Production Optimization under Injection of Biopolymer, Synthetic Polymer and Gels in a Heterogeneous Reservoir

Published: September 2016

Water injection increases the percentage of recovery by means of providing pressure support and displacing the oil in the heterogeneous porous medium. In such a displacement process, mobility ratio is important for a more efficient displacement of oil by the injected fluid where mobility ratio can be improved using the fluids involving gelling agents, resulting in increased volumetric sweep. While polymers degrade and break up upon experiencing sudden extreme shear stresses and temperatures, polymer macromolecules are forced to flow into narrow channels and pores, molecular scission processes can take place, thus it is of outmost importance to have a strong understanding of use of right type and amount of viscosity reduction agent.

For polymer injection, a comparison of xanthan polymer and synthetic polymer mechanisms was conducted. A commercial full-physics reservoir simulator is coupled with a robust optimization and uncertainty tool to run the model where a simplified gel kinetics is assumed to form a microgel with no redox catalyst. Water injection continues over all 6 layers for 450 days, followed by gel system injection for 150 days, in the bottom 2 layers. Water injection is continued to 4 years. The top four layers have higher horizontal permeabilities, and a high-permeability streak is at the bottom of the reservoir to reduce any helpful effects of gravity. Control and uncertainty variables are set to investigate the sensitivity under this process using the coupled optimization and uncertainty tool.

Results demonstrate deep penetration of gel and blocking of the high permeability bottom layers. Sensitivity studies indicate the relative merits of biopolymer, xanthan polymer in terms of viscosity effects vs synthetic PAM in terms of resistance factor vs insitu gelation treatments and their crossflow dependence. Adsorption and retention of polymer and gel are permeability dependent.

Considering the fact that there is a significant potential for application of gel solutions in the US and throughout the world, this study illustrates the relative advantages of different treatments in terms of viscosity reduction in the same model in a comparative way outlining the significance of each control and uncertainty variable for better management of reservoirs where displacement efficiency is very critical.
Oil- and Gas-Wellsite-Reclamation-Liability Estimation
Authors: Thiessen Ron J. , Achari Gopal
Published: September 2016

This paper examines abandoned-wellsite-reclamation-liability estimates under the Alberta Energy Regulator's (AER's) Licensee Liability Rating (LLR) Program. A statistical analysis of data from reclaimed wellsites in Alberta is conducted in this examination. A conclusion is that approximately one-half to two-thirds of wellsites have a reclamation liability that exceeds the generic value specified by the AER, and up to 5% of sites have a liability exceeding the AER value for problem sites. Also, a previous assertion that reclamation liability is a function of well type, well age, soil type, and land use is tested. The authors find that only well type is needed to predict reasonable reclamation liability of wellsites on agricultural land in Alberta. Given the 2016 economic situation in the Alberta oil and gas industry, the information in this paper may be useful in adjusting the required security under the LLR Program.

O sucesso desses sistemas está relacionado com alguns fatores, como o cultivo de espécies tolerantes ao sombreamento e práticas de manejo que permitam a sua produtividade. O objetivo deste trabalho foi avaliar o milho BRS 1030 cultivado sob influência de renques de paricá (Schizolobium amazonicum) em sistema de integração Lavoura-Pecuária-Floresta. O delineamento experimental utilizado foi o de blocos casualizados, com 4 repetições. Os tratamentos foram compostos por cultivo de milho consorciado com forragem (Brachiaria ruziziensis) em parcelas distantes 2,5 m, 5 m e 10 m em relação à linha de plantio do paricá com 3 anos de cultivo. Avaliou-se a altura de planta e espiga, a produção de grãos e estande de plantas. As variáveis altura de planta e altura de espiga não apresentaram diferença significativa em função da distância entre os renques de árvores. O sombreamento dos renques de paricá não afetou a produtividade de grãos (kg.ha-1 e saca.ha-1) do milho quando comparado as distâncias entre os renques de árvores e as linhas da cultura. Os renques de paricá com três anos de cultivo na área de estudo não afetou o desenvolvimento do milho em consórcio com forragem.

La formación crítica como fundamento pedagógico de los posgrados en educación
Authors: Muñoz Gaviria Diego Alejandro , Betancourt Cadavid Jorge Hernán
Published: September 2016

Este documento se confiere a sí mismo justificación académica, y a la vez política, porque considera la idea de ofrecer un texto que posibilite el debate en torno a la distinción y soberanía que un ámbito de formación universitaria denominado posgrados, en el campo de la educación ha de tener. En este sentido, pensar en términos amplios la universidad, y en términos restringidos los posgrados en educación, exige una reflexión sobre las condiciones pedagógicas y políticas que dan sentido a la llamada escuela de la investigación (Humboldt). Así pues, la distinción y la soberanía de posgrados en educación ponen de manifiesto la reflexión sobre el por qué hacemos lo que hacemos, y luego intentar reconstruir cómo hacemos lo que hacemos. La postura de este texto es de corte crítico teórico, en cuanto pretende ejercer la crítica en todas sus consecuencias, hasta llevarla al nivel más ético de su ejercicio: la autocrítica.

Este artículo presenta los contextos de origen del concepto competencia con el propósito de establecer una versión ampliada que permita reconocer su génesis en la lingüística, su desarrollo en la psicología cognitiva y su inserción al discurso neoliberal en la planificación de los sistemas escolares, desde el Estado hasta las empresas privadas. De esta manera, se propone un ámbito pedagógico que evidencia las contradicciones y posibilidades de este proyecto educativo, en el reconocimiento de la importancia de la evaluación para consolidar tales propuestas. Así, se plantea reemplazar la calificación por la evaluación, las competencias por la actuación, las fronteras disciplinares por la transdisciplinariedad, los tiempos curriculares por el de la indagación, el mundo neoliberal por el de la vida.

Published: September 2016

Después de definir qué se entiende por relato, el artículo resume en doce puntos esenciales lo que Jerome Bruner afirma sobre el arte de contar. Se estudian temas como la concepción interpretativa del arte de narrar, pasando –entre otros temas– por el estudio de la relación entre interioridad y exterioridad y relato, hasta llegar a la narración como un acto subversivo. Estas doce aristas configuran la noción de narración en el pensamiento de J. Bruner.

Configuración de subjetividades en los jóvenes universitarios sobre las Tecnologías de la Información, la Comunicación y del Aprendizaje (TIC/TAC)
Authors: Álvarez Quiroz Glenis Bibiana , Vélez de la Calle Claudia del Pilar
Published: September 2016

El presente artículo se centra en presentar la problematización de un proceso de investigación cuya finalidad es comprender como los jóvenes se relacionan educativamente con estas mediaciones y los sentidos y significados emergentes que permiten interpretar las subjetividades que producen educativa y socialmente en ellos. En cuanto a la metodología, el estudio es de tipo cualitativo, el diseño metodológico es estudio de casos y las técnicas de recolección de información son grupos focales y narrativas digitales con jóvenes universitarios de la ciudad de Montería, Colombia. Se parte del supuesto de reconocer que es evidente la inserción de las Tecnologías de la información y comunicación (TIC) en el mundo contemporáneo, y como ellas se han convertido en un dispositivo de agenciamiento de nuevas formas de vida y subjetividades; a la vez han cambiado la manera de los seres humanos de relacionarse con el mundo en aspectos tanto económicos, políticos, culturales como sociales, cognitivos y educativos (Gutiérrez y Orozco, 2007) 
La docencia universitaria: realidad compleja y en construcción. Miradas desde el estado del arte
Authors: Londoño Orozco Guillermo
Published: September 2016

El artículo sintetiza el estado del arte llevado a cabo en torno al tema de la docencia universitaria, considerando los puntos esenciales desde los cuales se ha tratado de abordar y comprender el tema: El contexto universitario actual; la didáctica universitaria; las prácticas docentes; la pedagogía universitaria y el saber pedagógico inmerso en ella; la formación docente; y, algunas caracterizaciones en relación con problemáticas que enfrentan los profesores universitarios, con referencias a experiencias exitosas y con ciertos acercamientos a la identidad docente. Todas estas aproximaciones, para hacer ver por un lado la amplitud y complejidad del tema y por otro, la necesidad de mayores desarrollos y estudios que no solo complementen trabajos tan importantes como los referenciados en este escrito, sino que orienten mayores comprensiones y conceptualizaciones sobre lo que debe significar la docencia universitaria en la educación superior del siglo XXI.
Ciudadanía y formación docente en el Norte del Cauca
Authors: Martínez Ruiz Víctor
Published: September 2016

Los avances del Ministerio de Educación de Colombia con relación a la cualificación docente contrastan con las necesidades formativas de los maestros y maestras en los municipios, y en particular,  con el de Puerto Tejada. De otra parte, el Plan de formación docente impulsado por el Departamento del Cauca prioriza los lineamientos nacionales por encima de las evidentes demandas contextuales,  relegando a un segundo plano el interés por la ciudadanía y la interculturalidad, aspectos fundamentales en medio de la pobreza y la violencia que vive el Norte de esta región. El diplomado, Formación ciudadana para la paz desde el desarrollo de habilidades para la vida y la interculturalidad, ofrecido por el autor en el curso de esta investigación doctoral responde a las necesidades educativas de los docentes de Puerto Tejada toda vez que apunta al fortalecimiento de capacidades para la convivencia social y hace evidente la ausencia de ofertas que respondan a la “formación en servicio” de los docentes.
Aproximación filosófico-pedagógica a la formación: Cuestiones histórico-conceptuales
Authors: Villa Holguín Edison , Patiño Gaviria Carlos Dario , Duque Luisa , Cardona Estrada John Jairo , Muñoz Gaviria Diego Alejandro
Published: September 2016

La formación ha sido pedagógica y filosóficamente un concepto problemático, dado que vincula en su historia la sintesis del pensamiento germano. La historia del concepto de formación puede ser ubicada en tres grandes periodos: el momento conservador – teológico de la primera mitad del siglo XVIII; el estatal – prusiano de la segunda mitad del siglo XVIII; y el neohumanista del siglo XIX, con sus consecuentes críticas. Para el siglo XX, esta historia permitirá generar una tradición en torno a las teorías de la formación: las teorías afirmativas o funcionales y las teorías no afirmativas o críticas. Aún queda por explorar las implicaciones del concepto de formación más allá de la tradición filosófico – pedagógica alemana, para pensar, por ejemplo, sus desarrollos en la tradición pedagógica latinoamericana.
La lectura y la escritura en los estudiantes de instituciones educativas de Medellín participantes en el programa Prensa Escuela
Authors: Peña Santodomingo Judith María , Castellano Ascencio Milton Daniel
Published: September 2016

El artículo aborda el tema de la lectura y de la escritura en el marco del programa Prensa Escuela. El objetivo del artículo es describir las transformaciones generadas en los procesos formativos, en la dimensión comunicativa, de los estudiantes de las instituciones educativas de Medellín que han participado en el Taller de Apoyo a Medios Escolares del programa Prensa Escuela durante el período 2012-2013. El método empleado corresponde a un estudio de casos múltiple inclusivo, que plantea el análisis de un fenómeno dentro de contextos diversos, que para este estudio los constituyen las instituciones educativas participantes en el programa durante el período 2012-2013. Los resultados del estudio muestran que la experiencia formativa del programa Prensa Escuela abre la posibilidad de abordar los procesos de lectura y escritura desde una visión contextualizada que vincula al mundo de la vida de los sujetos participantes, en la medida en que plantea prácticas de lectura y de escritura situadas en escenarios reales.
Influence of the fetch parameter on results from empirical correlations for estimating odorous emissions at passive liquid surfaces

Published: September 2016

Passive liquid surfaces in wastewater treatment plants may be potential sources of odorous emissions. This study investigates the occurrence and significance of deviations that may originate from the use of the effective diameter as fetch parameter in the empirical correlations utilised by the WATER9 model to estimate odorous emissions at passive liquid surfaces. A sensitivity analysis was performed using benzene as a model compound and considering representative conditions of wind speed and wind alignment. The gas-film mass transfer coefficient (kG) was found relatively in sensitive to the choice of the fetch parameter, deviating less than 15% for aspect rations up to 15. The calculation of the liquid-film mass transfer coefficient (kL) was much more sensitive (positive extreme of 126.98% and negative extreme of −54.80%), partially because of the use of different equations for different fetch-to-depth ratios. For more volatile compounds, such as benzene, these discrepancies will be significantly manifested in the estimated emission rate. When appropriate, the use of the actual fetch instead of the effective diameter is recommended.

El objetivo primario fue determinar los indicadores como estrategia para gestionar la investigación, y como resultado, deﬁnir un valor recomendable de visitantes que el destino debería recibir diariamente. La investigación fue ﬁnanciada por la Universidad de Quintana Roo.
La variable ambiental y el cambio de paradigmas dentro de los currículos universitarios
Authors: Valderrama Martínez Jorge Antonio , Velázquez Romero María Guadalupe
Published: September 2016

El trabajo se inicia con una reﬂexión general en torno a la trayectoria de algunas instituciones de educación superior mexicanas que han incluido la dimensión ambiental a la estructura de sus programas, reconociendo su acción-proyección desarrollada a través de la conformación de comités, agendas, programas especializados, estructuras de docencia, investigación y extensión universitaria. Actualmente la ambientalización del currículo universitario tiene necesariamente que ver con programas ligados a valores, aspectos teóricos, prácticas individuales y colectivas, que generen como resultado de procesos integrados de construcción de conocimiento, aprendizajes signiﬁcativos que no sólo se evidencien en una mayor conciencia socio-económica-ambiental, sino de manera preferente como propuesta de atención y acción por parte de los universitarios.
