Le solo imprévu : l?atelier d?improvisation comme lieu d?échanges entre cultures d?audition

2021

Starting from sociologist Anne-Marie Green?s idea of ?common space?, and from Hans Robert Hauss? reception theory, the improvisation workshop is thought to be a way of transforming the practices of reception, in order to modify the nature of the culture of listening of each listener. Four research axis are, then, proposed, from the validation of the personal experience of the participants to the reception of the instant?s surprise as a factor of education, including the research of communicational tools specific to reception of music, capable of captivating the listeners with the original aspects of the unknown musical territories.

Validare le pratiche collaborative per l’economia circolare urbana: il punto di vista del design.

2021

The article presents the results of the research activity carried out within the framework of the European project H2020 REFLOW, which aims to build an integrated approach for the development of innovative participatory practices dedicated to urban circular metabolisms. As a result of the survey conducted on the application of collaborative models for the urban circular economy, it emerged that there is no shared operational strategy that can be adopted for the circular development of complex systems, such as cities. Based on this premise, this paper offers a new perspective on how to build and validate a transitional pathway for the development of circular cities through the adoption of a …

Elaboración un instrumento para conocer las características de la banda sonora de la programación infantil de televisión

2014

Television is one of the most important elements in the construction of the musical and audible reality of children and teenagers. It offers a selected and edited version of a musical environment, with an indisputable level of communicative and patrimonial influence. This paper is part of a research project that sets out to know what children are listening to in children’s television programming, in a sample of Latin American television coverage. The general objective has been to establish the parameters of everyday listening experiences and to create an instrument which is able to determine the objective elements of listening environments through their most notable medium: the soundtrack o…

Estructura factorial y propiedades psicométricas de la time management behavior scale (TMBS) en población universitaria colombiana

2017

Se investigó la estructura factorial de la Time Management Behavior Scale (TMBS) en universitarios colombianos. La gestión del tiempo es un importante predictor del logro estudiantil y clave para la disminución de la deserción universitaria. Participaron 494 estudiantes de primer año de nueve programas en dos universidades de la ciudad de Bogotá. Se comprueba una estructura multidimensional de cuatro subescalas que explicaron el 42.68 % de la varianza total. Se obtuvieron índices de consistencia interna por encima de 0.7 en tres factores y una fiabilidad global de 0.84. Coincidiendo con investigaciones previas, frente a los hombres, las mujeres obtienen puntuaciones superiores en dos de las…

Validation procedures in radiological diagnostic models. Neural network and logistic regression

1999

The objective of this paper is to compare the performance of two predictive radiological models, logistic regression (LR) and neural network (NN), with five different resampling methods. One hundred and sixty-seven patients with proven calvarial lesions as the only known disease were enrolled. Clinical and CT data were used for LR and NN models. Both models were developed with cross validation, leave-one-out and three different bootstrap algorithms. The final results of each model were compared with error rate and the area under receiver operating characteristic curves (Az). The neural network obtained statistically higher Az than LR with cross validation. The remaining resampling validatio…

Validating a Test for Measuring Knowledge and Understanding of Economics Among University Students

2019

Abstract. University students' knowledge and understanding of economics have mostly been investigated cross-sectionally; however, longitudinal analyses are needed to determine which factors influence knowledge development and to draw valid conclusions based on test results. In the WiWiKom II project, a quasi-experimental longitudinal study was conducted assessing bachelor students of business and economics over the course of their studies in Germany (N = 39 universities). In this project, running from 2016 – 2019, the test-takers complete the WiWiKom II-test of economic knowledge (adapted TUCE4G and TEL4G items) and a general cognitive ability test (BEFKI 11) at four measurement points, ea…

Real-Time Photoplethysmography Imaging System

2011

Real-time non-contact photoplethysmography imaging (PPGI) system for high-resolution blood perfusion mapping in human skin has been proposed. The PPGI system comprises of LED lamp, webcam and computer with video processing software. The purpose of this study is to evaluate the reliability of the PPGI system when measuring blood perfusion. The validation study of PPGI and laser-Doppler perfusion imager (LDPI) was performed during local warming of palm skin. Results showed that the amplitude of PPGI increases immediately after warming and well correlated with the mean LDPI amplitude (R=0.92+-0.03, p<0.0001). We found that PPGI technique has good potential for non-contact monitoring of blood p…

Heart rate responses during the modified six-minute walk test among Special Olympics athletes

2021

Objective: The construct validity of the modified six-minute walk test (m6MWT) was examined by addressing the following questions: 1) do participants attain a steady state plateau in heart rate (HR) within the range of 110-150 beats per minute? 2) at what percentage of their predicted HR maximum were participants during each minute of the test? Material and Methods: Participants were 36 (male=56%) Special Olympics athletes aged 34.4 years (SD = 12.7). Following familiarization, participants completed the m6MWT while wearing a Polar Team 2 heart rate monitor. Results: By the end of the first minute, average heart rate was 120bpm, and a factorial repeated measures ANOVA revealed that steady s…

Draining and drying process development of the Tokamak Cooling Water System of ITER

2016

Abstract The ITER Organization (IO) developed a thermal-hydraulic (TH) model of the complex first wall and blanket (FW/BLK) cooling channels to determine gas flow rate and pressure required to effectively blow out the water in the FW/BLK. In addition, US ITER conducted experiments for selected geometries of FW/BLK flow channels to predict the blowout parameters. The analysis indicates that as low as 2 MPa of pressure difference over the blanket modules will ensure substantial evacuation of the water in blankets with just a few percent remaining in the blanket flow channels. A limited validation study indicates that the analysis yields less conservative results to compare against data collec…
