Soil emissivity and reflectance spectra measurements
2009
We present an analysis of the laboratory reflectance and emissivity spectra of 11 soil samples collected on different field campaigns carried out over a diverse suite of test sites in Europe, North Africa, and South America from 2002 to 2008. Hemispherical reflectance spectra were measured from 2.0 to 14 microm with a Fourier transform infrared spectrometer, and x-ray diffraction analysis (XRD) was used to determine the mineralogical phases of the soil samples. Emissivity spectra were obtained from the hemispherical reflectance measurements using Kirchhoff's law and compared with in situ radiance measurements obtained with a CIMEL Electronique CE312-2 thermal radiometer and converted to emi…
Comparison between different sources of atmospheric profiles for land surface temperature retrieval from single channel thermal infrared data
2012
Abstract Different sources of atmospheric water vapor and temperature profiles were used with a radiative transfer model for retrieving land surface temperature (LST) from thermal infrared remote sensing data with the so-called single channel (SC) method. Retrieved LSTs were compared to concurrent ground measurements over homogeneous rice fields to assess the accuracy of the atmospheric profiles. These included radiosonde balloons launched at the test site near-concurrently to satellite overpasses, re-analysis profiles from the National Centers for Environmental Prediction (NCEP), and satellite sounder products from the Atmospheric Infrared Sounder (AIRS) and the Moderate Imaging Spectrorad…

Abstract This article considers the implementation of a new learning subject ”Technology Comprehension” into lower secondary schools in Denmark, as part of an initiative by the Danish Ministry of Education. The subject consists of learning objectives related to computing, design, and societal reflection and was first introduced as an elective course in 13 schools to investigate how it could be integrated into the Danish education system. We present four key findings based on school visits, interviews, an electronical survey, two questionnaires, and workshops including theme discussions: (1) teachers did not perceive Technology Comprehension as a distinct subject, but rather as a set of skil…
Recognition, Work, Treatment
2017
The article I am going to propose is a reflection on the theme of recognition in working and social contexts, and focuses on problems and troubles people cope with in this historical moment. This is a period during which reciprocity and recognition relationships involving our education and work career seem to have no more value, because the world of work now focuses on involving people in production and does not care about involved subjects' life plans. I also wish to point out risks and sufferance affecting subjects who perceive with always greater precision that they are more and more often oppressed by labor and mind exploitation, rather than considered human resources with a working com…
Towards a Modelization of the elusive Concept of Wisdom using Fuzzy Techniques
2012
After having been a term of reflection in philosophy as well as psychology for ages, the fascination with human wisdom finally reaches the realms of computer science. In comparison to the first philosophical definition attempts, that date back to Aristotle (384 BC – 322BC), the efforts in information science during the late 1980s seem quite recent. Nevertheless have there been astonishing new insights provided by cognitive science since those first formal modelizations were designed – findings that strongly suggest a reconsideration of our current formalization of wisdom in the computer science domain. We suggest to establish a new, integrated view on the concept of wisdom, using the insigh…
Evaluación de la educación digital y digitalización de la evaluación
2021
La evaluación de la educación digital y digitalización de la evaluación son procesos por el que transita tanto la educación digital como la educación digital de emergencia. Aunque el tema de la evaluación, por sí misma, ya es complejo, esta complejidad aumenta cuando media la tecnología digital. Lejos de pensar que se trata de una acción técnica, la evaluación digital y la digitalización de la evaluación, como lo demuestra el contenido de este monográfico, no se reducen a la inserción de sistemas tecnológicos, sino a la comprensión pedagógica de su rol e impacto en los procesos educativos. Los trabajos que conforman este monográfico buscan contribuir, desde el análisis empírico y la reflexi…
Recurrence Quantification Analysis as a Methodological Innovation for School Improvement Research
2021
Contains fulltext : 240653.pdf (Publisher’s version ) (Closed access) School improvement and educational change can be facilitated by learning through reflection, as this allows teachers to discover ways to develop and adapt to change. Higher levels of engagement in reflection have been found to be beneficial, but it is unclear from which everyday routine in engagement in reflection higher levels arise, and thus whether occasions to make knowledge explicit should be organized with a certain constancy. In this study, we therefore used a conceptualization of teacher learning through reflection as a situated and dynamic process in which available environmental information, learning activities,…
Today's news — tomorrow's context: A dynamic model of news processing
1997
We are proposing a feedback model of news processing, assuming that news reception is guided by media input as well as by existing cognitive structures. However, these structures are in turn shaped by former media coverage. In our study we examine viewers’ processing of TV news, comparing objective news content (content analysis) to subjective meaning of news stories (viewer interviews). Results show that viewers interpret information about new events in the context of past events, themselves mainly a reflection of former media coverage.
Análisis de materiales didácticos digitales para guiar y/o apoyar el proceso de enseñanza - aprendizaje de las matemáticas
2018
Las tecnologías digitales han supuesto una revolución en todos los ámbitos de la vida: tecnológico, empresarial, comunicativo, cultural, e incluso en el conocimiento y el entretenimiento. En el panorama educativo tiene también su reflejo y las metodologías y recursos se han redibujado, en cuanto a los diferentes soportes, canales, lenguajes, narrativas,? Estos cambios, sustantivos y profundos, afectan simultáneamente al profesorado, alumnado y familias, pero otros agentes como las administraciones educativas y el sector editorial también se ve involucrado. En esta investigación analizamos una muestra de portales institucionales y plataformas comerciales que ofertan recursos didácticos digit…
Computing and communication convergence reflection to legislation system and higher education programs
2017
Concept of computing and communication convergence has many years of history — as strategic concept it started about 1977 and yet have many definitions. The idea behind convergence concept mostly related to getting closer computing and telecommunication common technologies, services and service provider's business models. In this academic position paper some less significant obstacles of influence-reflection of convergence to legislation system, higher education programs and industry labor market are discussed.
