Monitoring Water Surface and Level of a Reservoir Using Different Remote Sensing Approaches and Comparison with Dam Displacements Evaluated via GNSS
2018
Remote sensing allowed monitoring the reservoir water level by estimating its surface extension. Surface extension has been estimated using different approaches, employing both optical (Landsat 5 TM, Landsat 7 ETM+ SLC-Off, Landsat 8 OLI-TIRS and ASTER images) and Synthetic Aperture Radar (SAR) images (Cosmo SkyMed and TerraSAR-X). Images were characterized by different acquisition modes, geometric and spectral resolutions, allowing the evaluation of alternative and/or complementary techniques. For each kind of image, two techniques have been tested: The first based on an unsupervised classification and suitable to automate the process, the second based on visual matching with contour lines…
Fazer pós-graduação em educação em ciências melhora o ensino?
2018
espanolEn este articulo se indaga como influye el transito por dos maestrias en educacion en ciencias y tecnologia de Cordoba y La Plata (Argentina) en el desempenode docentes cursantes a las mismas. Nuestra hipotesis fue que dicho transito debia mejorar sus practicas y sus habilidades de investigacion. Para tal fin se hicieron preguntas a estos docentes, relacionadas con sus practicas y con los cambios que pueden haber sido promovidos por dichos estudios de posgrado. Ello se complemento con observaciones a sus clases. Los resultados muestran que la maestria genero modificaciones en la practica docente, que desarrollo o perfecciono sus habilidades de investigacion educativa y que la partici…
MEDIA SKILLS AND PROFESSIONAL AWARENESS IN TEACHER TRAINING
2016
The present paper documents the use of an e-portfolio to promote a process of reflection on the digital skills of in-service teachers. Teachers have been involved for 75 hours in experiencing a training methodology for the promotion of media skills necessary to design paths of media education. The use of the e-portfolio as a means of course assessment was evaluated by the participating group of 91 trainee teachers. The methods of data collection took the form of an analysis carried out thanks to the use of a check list with 22 indicators deduced from the research, of which the frequency was observed. The analysis of the e-portfolios revealed a high trainee teachers’ ability to recognize the…
Discussing the Concepts of Cluster and Industrial District
2016
The significance and popularity of the cluster and industrial district concepts claim for a deeper reflection. The analysis of one of the European Commission’s (EC) policy documents shows inconsistencies that do not impede the formulation of normative statements. That way we answer the question of why and how cluster ideas have substituted industrial district principles and the consequences derived from that phenomenon.
DISCUSSION ON THE RELATIONSHIP BETWEEN DEEP SEISMIC REFLECTION PATTERNS AND TECTONIC UNITS OF THE EASTERN PART OF THE CENTRAL ASIAN OROGENIC BELT IN …
2017
Division of tectonic units in the eastern part of the Central Asian Orogenic Belt in northeast China has been a major concern and resulted in much fieldwork, but the division of these tectonic units in NE China is still controversial. Although detection of tectonic units in seismic sections is not straightforward, for this meeting, we shall try to relate tectonic units with the crustal and upper mantle structure and deformation derived from a ~2500 km long reflection seismic profile (Figure, red lines) in this area, recently acquired or reprocessed with support of China Geological Survey and the Chinese SinoProbe Project.
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…
Synthesis and Characterization of Iron-Doped ZrSiO4 Solid Solutions from Gels
2011
The mechanism of formation and the structural features of tetragonal Fe–ZrO2-amorphous silica composites and particulated Fe-doped ZrSiO4 solid solutions were studied. A series of specimens with compositions Fex–ZrSiO4, 0 ≤ x ≤ 0.10 were prepared by sol–gel techniques and thermally annealed over the range of temperature between 400°C and 1600°C. Results confirmed the formation of tetragonal Fe–ZrO2 solid solution as first crystalline phase on the whole process leading to Fe-doped ZrSiO4 solid solution. The annealing temperature for the preparation of Fe-containing ZrSiO4 solid solutions was dependent on the nominal amount of iron. The Fex–ZrSiO4 solid solutions, with 0.02 < x < 0.08, were a…
Reflection Assignment as a Tool to Support Students’ Metacognitive Awareness in the Context of Computer-Supported Collaborative Learning
2021
The present study explores the potential of a reflection assignment as a tool for supporting master’s degree students’ metacognitive skills in the context of computer-supported collaborative learning (CSCL). The research question (RQ) is formulated as follows: How does a regularly submitted reflection assignment support the development of students’ individual metacognitive awareness in the context of CSCL? The empirical data is a text corpus (7878 words) extracted from individual students’ (N = 13) reflection assignments (N = 65) submitted during one semester. Qualitative content analysis was employed to analyze the data. The results demonstrate that by the end of the course, the students s…
IL LEGISLATORE TEDESCO ALLARGA LE MAGLIE DELLA REVISIONE CONTRA REUM: L'ASSOLUZIONE PER DELITTI GRAVI E IMPRESCRITTIBILI PUÒ ESSERE MESSA IN DISCUSSI…
2022
Il legislatore tedesco ha ampliato il novero dei casi di revisione in peius. Ha previsto la possibilità di impugnare una sentenza definitiva di assoluzione per omicidio o crimini internazionali, qualora – in base a nuovi fatti o mezzi di prova – emergano “ragioni stringenti” per una condanna. La riforma ha già sollecitato dubbi di legittimità costituzionale e, per la sua rilevanza, suscita varie riflessioni.
Design e narrazioni
2022
Il testo nasce dall’esigenza di mettere a fuoco le implicazioni cognitive, metodologiche e progettuali del concetto di narrazione, sempre più ricorrente nella nostra esperienza quotidiana soprattutto per le molteplici forme di comunicazione e di produzioni culturali che vi si ispirano; si tratta di un concetto che anche nella riflessione teorica e nella progettualità del design sta alimentando dimensioni fortemente innovative ed evolutive nella costruzione, comunicazione di significati, contenuti immateriali, esperienze e valori emozionali che si sovrappongono e s’intrecciano all’espressione tangibile e funzionale degli oggetti, degli artefatti comunicativi, degli spazi. Si propone un perco…
