    Web-based feedback system: the life cycle management as continuous maintenance of apartment facility information

    Get PDF
    This research investigates the feasibility of web technology as a means of delivering facility information for better support of facility operations and maintenance. This study proposes a web-based feedback system as a pragmatic solution to the limitations of current facility management (FM) processes, increasing the efficiency of these processes via web technology. In practice, work orders and records are often misplaced, resulting in reduced efficiencies, redundancies, and time-consuming, costly tasks. This problem may be overcome by use of a system that stores information digitally and provides a web-based interface. The interface could allow operations personnel to create documentation, share and monitor work orders, provide feedback for service online, and facilitate communication between facility teams. The benefit for a FM department is that it can receive feedback on performance, which would improve the quality of service and build a record of practical experiences. In this research, the software was tested using two types of prototype testing: first, system testing to evaluate functionality, usability and capability; and second, a post-task questionnaire survey was conducted to test and review the concept, interface, and usability of the system. Facility Management Industry Advisor Council (FMIAC) members answered the questionnaires after using the system posted on the web. By using web-based feedback system, a facility web site can be created and maintained easily through a standard web browser. The questionnaires from the FMIAC members were analyzed to test research questions. The tests show that the software aids facilities managers in maintaining living documents of their facilities

    Intensification of terrestrial carbon cycle related to El Nino-Southern Oscillation under greenhouse warming

    Get PDF
    The El Nino/Southern Oscillation (ENSO) drives interannual variation in the global carbon cycle. However, the relationship between ENSO and the carbon cycle can be modulated by climate change due to anthropogenic forcing. We show herein that the sensitivity of the terrestrial carbon flux to ENSO will be enhanced under greenhouse warming by 44% (+/- 15%), indicating a future amplification of carbon-climate interactions. Separating the contributions of the changes in carbon sensitivity reveals that the response of land surface temperature to ENSO and the sensitivity of gross primary production to local temperature are significantly enhanced under greenhouse warming, thereby amplifying the ENSO-carbon-cycle coupling. In a warm climate, depletion of soil moisture increases temperature response in a given ENSO event. These findings suggest that the ENSO-related carbon cycle will be enhanced by hydroclimate changes caused by anthropogenic forcing.113Ysciescopu

    Get PDF
    Este trabajo presenta un modelo web ideado para asesorar en la toma de decisiones en la integración de construcciones turísticas rurales en su entorno, mediante el intercambio de información y colaboración entre los agentes implicados. Se expone el uso de metodologías espaciales para la selección de localizaciones adecuadas a partir de la evaluación de criterios múltiples (ECM) en un marco web. Se emplean cuatro criterios para la evaluación, que se muestran en un mapa final global de idoneidad, basado en cuatro mapas intermedios parciales según los criterios de evaluación. Como resultado se utilizan tres niveles de información: página de información general, página para la toma de decisión espacial multi-criterio y una página con mapas de intercambio de conocimiento. El modelo propuesto, aplicado al caso práctico de ‘Hervás’, pretende conseguir una discusión esclarecedora entre distintas percepciones de integración de construcciones en su entorno, consi¬derando diferentes alternativas de decisión y posibles contribucionesThis paper presents an interoperable web-based model able to interchange information amongst different stakeholders and to use the information as a means of promoting collaborative activities to integrate rural tourism buildings into a landscape with a case study, Hervás (Spain). Preliminary results from a continuing research are explained with a spatial methodology for selecting the suitable locations of rural buildings, coupling multi-criteria evaluations (MCE) into a web framework. The aim of this methodology is to classify four evaluation criteria and then is to show a final composite suitability map based on the four intermediate maps. The model deals with three types of information: a general overview page; a multi-criteria spatial decision-supporting page; and, a knowledge sharing map page. Using the proposed model, the regional spatial planning is intended to discuss different perceptions of building integration with the surroundings from various decision alternatives and to elucidate this model’s contribution.-- Ministerio de Ciencia e Innovación (Proyecto BIA 2007-61166)peerReviewe

    La relativamente nueva metodología, el aula volteada, es una de las metodologías de instrucción de aprendizaje mixto en la que se invierte el aula tradicional. Esta metodología afirma que los estudiantes pueden participar y comprometerse más exitosamente en su clase y pueden lograr un mejor aprendizaje cuando su aula está volteada. Este trabajo presenta un estudio de dos años de duración para medir los efectos del modelo de aula invertida en el rendimiento, las percepciones y las emociones de los estudiantes de formación de profesores en educación científica. En particular, esta investigación se llevó a cabo durante dos cursos, 2014/2015 y 2015/2016, en una asignatura de ciencias generales. Con un cuestionario post-tarea, obtuvimos la información para evaluar su desempeño, percepciones y emociones, hacia la clase. Los resultados confirmaron que se encontró una diferencia estadísticamente significativa en todas las evaluaciones con los estudiantes del modelo de aula volteada, con un rendimiento superior en promedio, mostrando percepciones favorables y demostrando emociones positivas sobre el modelo de aula volteada. Por lo tanto, los estudiantes estaban listos para tomar más cursos siguiendo el modelo de aula invertida. Los resultados obtenidos en este estudio muestran una prometedora inclinación sobre el rendimiento, las percepciones y las emociones de los estudiantes hacia la metodología del aula volteada, y darán un nuevo impulso a esta metodología de instrucción relativamente nueva.The relatively new methodology, flipped-classroom, is one of blended learning instruction methodologies in which the traditional-classroom is inverted. This methodology asserts that students can participate and engage more successfully in their class and can attain better learning when their classroom is flipped. This work presents a two-year study to measure the effects of the flipped-classroom model on the performance, perceptions, and emotions for teacher training students in science education. Particularly, this research was carried out during two courses, 2014/2015 and 2015/2016, in a general science subject. With a post-task questionnaire, we obtained the information to assess their performance, perceptions, and emotions, toward the class. The results confirmed that a statistically significant difference was found on all assessments with the flipped-classroom students, performing higher on average, showing favorable perceptions, and demonstrating positive emotions about the flipped-classroom model. Thus, the students were ready to take more courses pursuing a flipped-classroom model. The results achieved in this study show a promising inclination about the performance, perceptions, and emotions of students toward the flipped-classroom methodology, and will provide an entirely a new impetus for this relatively new instruction methodology.• Ministerio de Economía y Competitividad y Fondos FEDER.

    Virtual escape room and STEM content: effects on the affective domain on teacher trainees

    Get PDF
    In recent times, there has been growing disinterest by students in STEM disciplines (science, technology, engineering, and mathematics). This trend is especially acute in those students who do not take STEM content during their secondary or high school education. This disinterest might be conditioned by negative emotions towards science developed by students during the different educational stages, even from an early age. In this sense, active teaching methodologies, such as gamification, play a fundamental role in fostering positive emotions towards learning STEM content. Within the wide range of gamification methodologies, we find educational Escape Rooms. Due to the current situation generated by COVID-19, many of the lessons have had to be adapted to a virtual format through various online platforms. In this study, in a preliminary manner, we aim to analyze the effects on the affective domain produced by a virtual Escape Room used in a STEM course as an instructional tool to teach contents about the Universe to teachers in training. According to the results obtained, the positive emotions of “happiness”, “satisfaction” and “fun” are significantly increased after the intervention. At the same time, some negative emotions, such as “nervousness”, “frustration” and “worry” also increase, partly due to the components typically found in this type of games. Based on these results, it is concluded that, despite the existence of both positive and negative emotions, the results are promising and the intervention is motivating and stimulating for the studentsPeer Reviewe

    Role of local air‐sea interaction in fire activity over Equatorial Asia

    Get PDF
    Fire activity in Equatorial Asia shows large interannual variability. Teleconnections by El Nino-Southern Oscillation and Indian Ocean Dipole are linked to drought and fire events; however, we found here that significant role of local Sea Surface Temperature (SST) over the Banda Sea in interannual variability of Equatorial Asian burned area in October even after removing the linear effects of teleconnections. October is the transient period from dry to wet season and strengthened seasonal circulation in October leads to a negative SST anomaly through Wind-Evaporation-SST mechanism. This anomalous local air-sea interaction sustains the dry season into October and stronger fire activity. Moreover, we found that the sensitivity of precipitation to SST is higher in October than in other months, hence fires in Equatorial Asia can be sensitively driven by local SST changes. Identification of this sensitivity will underpin better predictions of fire activity and air quality in Equatorial Asia.11Nsciescopu

    La toma de decisiones es una tarea que se realiza continuamente. Para considerar aspectos espaciales y multi-criterio en este estudio, se propone un sistema web de apoyo a la toma de decisión espacial multi-criterio (SADE-MC). Este trabajo presenta un sistema web de verificación SADE-MC, estableciéndose dos vías de participación, basado en los resultados obtenidos previamente. Así, se persigue contrastar la idoneidad de la disposición de edificaciones sostenibles en el entorno rural extremeño. Para ello, se evalúa la percepción resultante de los datos procedentes de dos vías de participación de cinco grupos (G1 a G5) a ravés de diagramas de radar, observándose una respuesta opuesta a la integración de construcciones entre G1 y G5. Así, se evidencia la necesidad de facilitar ayuda a la hora de establecer los posibles usos del suelo y proponer diferentes alternativas mediante herramientas precisas y eficientes, además de la posibilidad de ser aplicadas en diferentes situaciones.People are undertaking various decision problems daily.

In this work, it aims at examining the suitability of sustainable building arrangements that have occurred in Extremadura rural landscapes. With qualitative two-way content and survey data, the results described radar diagrams reflecting the different perception of public and academic participation groups (G1 to G5). Specifically, G4 expressed more positive responses to building integration while G5 showed the opposite responses. Thus, it is fundamental to help proper land-uses and decision alternatives through accurate and efficient tool, and to be able to apply other destinations.• Programa Juan de la Cierva Formación.
