Attitudes and perceptions of faculty members in the process adopting innovation: The OpenCourseWare initiative at the University of Valencia, Spain
2014
The OpenCourseWare project, an open learning resource repository, was established at the University of Valencia between 2008 and2009. It initially consisted of only 10 subjects, none of which was in the field of Health Sciences. The objective of this research was toinvestigate the attitudes and perceptions of faculty members in the field of Health Sciences with regard to the project to identify strategies to increase its use and expand its coverage. We applied Rogers’ innovation-diffusion theory along with a qualitative approach using theoretical sampling, semi-structured interviews and open coding. The results indicate the existence of two categories of faculty members. In the first group,…
Percepcions al voltant del coordinador TIC als Centres Educatius Intel·ligents. Un estudi de cas
2021
Este trabajo muestra las conclusiones de un estudio que tiene por objeto de análisis al coordinador TIC de un centro educativo y las percepciones, tanto del propio coordinador como de los docentes del centro, sobre sus funciones y tareas. La peculiaridad de este caso radica en que desarrolla su actividad profesional en un centro que participa en el programa de Centros Educativos Inteligentes (CEI), clasificado como Centro de Acción Educativa Singular (CAES). Los resultados aquí obtenidos forman parte de un estudio más amplio que examina las controversias a las que se enfrentan los coordinadores TIC de los CEI, modelo de integración de las TIC paralelo al modelo 1 a 1 y que ha sido experimen…
Estimación del impacto económico de los museos a través de las nuevas tecnologías de la información: el caso del museo Ene.Térmica
2015
It is increasingly necessary to emphasize the potential of culture as an engine for economic development and its ability to generateincome and create jobs. For this reason, this paper evaluates the economic impact of the Ene.térmica museum in the territory in which it is located, Ponferrada (Castilla y León Community, Spain). In order to achieve this aim, the estimation of the different types of effects needed to determine the impact of economic of the activities linked to the existence of Ene.Térmica is calculated by using the tool Impactrimonio, a web-based application that applies the Input-Output Tables methodology. The results show that due to both activities of the museum and demand f…
A Simple Fusion Method for Image Time Series Based on the Estimation of Image Temporal Validity
2015
High-spatial-resolution satellites usually have the constraint of a low temporal frequency, which leads to long periods without information in cloudy areas. Furthermore, low-spatial-resolution satellites have higher revisit cycles. Combining information from high- and low- spatial-resolution satellites is thought a key factor for studies that require dense time series of high-resolution images, e.g., crop monitoring. There are several fusion methods in the bibliography, but they are time-consuming and complicated to implement. Moreover, the local evaluation of the fused images is rarely analyzed. In this paper, we present a simple and fast fusion method based on a weighted average of two in…
Acorn Ants May Create and Use Two Entrances to the Nest Cavity
2021
Many ant species construct large nests that are inhabited by numerous workers, but other species dwell in ready-for-use cavities and live in small colonies. Ants of the genus Temnothorax inhabit small cavities, e.g., in acorns, twigs, and under rocks. Although a preference for nest sites with a narrower entrance is known, recent studies have shown that they also use cavities with wider entrances and may modify the size of such entrances. As good cavities for nest sites are a limited resource, the possibility to modify a potential nest site, including a reduction in the size of the hole, should be a favorable matter for the ants. Through field and laboratory experiments, I studied the acorn …
The Air-Ténéré National Natural Reserve (RNNAT) Observatory: Territorial Intelligence for Sustainable Development
2007
International audience; The Aïr-Ténéré National Natural Reserve is a protected area in which conservation and development principles tempt to be combined (co-management). To follow-up environmental changes which determine people's life, and to support decisions to manage the Reserve, the first steps of a territorial observatory are introduced. Beyond the technical build up of the Geographical Information System (GIS), the prototype proposed here is a concrete expression of a part of a territorial intelligent tool. It embraces all territorial dimensions from spatial to actors ones, and try in the context of the reserve, to revisit the definition of local governance. This work is based on a m…
Processes of Reflection in the Teaching and Learning Research Lab: Effects of Reflecting on Classroom Actions
2021
The ability to reflect on teaching is crucially important for the professionalization of trainee teachers. The fostering of reflection processes – by means of the systematic analysis of one’s own and others’ teaching from subject-specific, methodological, and educational science perspectives – plays a central role in a continuing and consecutive two-semester teacher training seminar concept at the University of Mainz. This paper explores the different effects of reflection on teaching on the basis of a quasi-experimental pre-post test design. Additionally, it shows how systematic reflection on teaching affects the students’ subjective experience of competence as well as the extent the semin…
Inverse Malthusianism and Recycling Economics: The Case of the Textile Industry
2020
The current use of natural resources in the textile industry leads us to introduce a new economic concept called inverse Malthusianism describing a context in which population grows linearly and resource consumption grows exponentially. Inverse Malthusianism implies an exponential increase in environmental impact that recycling may contribute to reduce. Our main goal is to extend the analysis of materials selection under the principle of equimarginality proposed by Jevons. As a first result, we show the particular circumstances under which policies excluding recycled supplies are never optimal. We also aim to overcome the difficulties of reducing environmental aspects to monetary units. To …
La Seconda Vita dell'Ambiente Costruito
2021
Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…
