Energy intensity in road freight transport of heavy goods vehicles in Spain

This paper examines the factors that have influenced the energy intensity trend of the Spanish road freight transport of heavy goods vehicles over the period 1996-2012. This article aims to contribute to a better understanding of these factors and to inform the design of measures to improve energy efficiency in road freight transport. The paper uses both annual single-period and chained multi-period multiplicative LMDI-II decomposition analysis. The results suggest that the decrease in the energy intensity of Spanish road freight in the period is explained by the change in the real energy intensity index (lower energy consumption per tonne-kilometre transported), which is partially offset by the behaviour of the structural index (greater share in freight transport of those commodities the transportation of which is more energy intensive). The change in energy intensity is analysed in more depth by quantifying the contribution of each commodity through the attribution of changes in Divisiaindices

Driving factors of GHG emissions in the EU transport activity

This research analyzes the importance of population, economic activity, transport volume and structural characteristics of transport activity-in terms of transport energy intensity, of transport modes' share and of energy sources' mix-as driving factors of greenhouse gas emissions in transport activity in the EU-28 during the period 1990-2014. The analysis is based on the STIRPAT model, which is broadened to investigate in depth the impact on transport emissions of changes in the transport activity and in the whole economy. Using panel data econometric techniques, the significance of each factor and the impact of its change on emissions are identified. A better knowledge of the key driving forces is crucial for implementing policies focused on successfully reducing emissions in transport activity. The results allow a preliminary assessment of the potential effectiveness of the 2011 Transport White Paper measures aimed at cutting transport emissions

Driving factors of GHG emissions in EU transport activity

This research identifies the driving factors of greenhouse gas emissions in transport activity in the EU-28 and the contribution of each of them to its changes during the period 1990-2014. The analysis is based on the STIRPAT model, which is broadened to investigate in depth the impact on transport emissions of changes in the transport activity and in the whole economy.

Relato de uma experiência inovadora de ensino religioso no CEPARL

Reflect upon the use of ICT as a means of constructing knowledge in High School (HS) at Colégio Estadual Professora Alcina Rodrigues Lima, a pioneer school in the project Ensino Médio Inovador (Innovative High School), by means of the results of the Religious Studies (RS) project “Visiting the historic, touristic and religious sites in Brazil”, started in 2010. From the data collected in the questionnaires, the use and behavior vis a vis the ICT in the Innovative High School and Traditional High School. The analysis was made under the light of the theories of scholars in the area of ICT such as Moram, Ferres, Prado and in the area of learning: Piaget, Vigotsky, Moura. Although the results of students and teachers who took part in the RS project were positive, and some of the students have shown their insertion in the world of educative technologies, one can also perceive that some of the students still find it difficult to integrate this world of ICT, want and need help; others wish to use such technologies, but they have no means for that and face the problems of the poor quality of the school‟s technological system and the lack of supportive staff at the CT lab.Reflete sobre o uso das TIC como meio construtivo de conhecimentos no Ensino Médio (EM) no Colégio Estadual Professora Alcina Rodrigues Lima, escola piloto do Ensino Médio Inovador (EMI), através dos resultados do projeto de Ensino Religioso (ER) “Conhecendo os lugares históricos, turísticos e religiosos do Brasil”, iniciado em 2010. Analisou-se com os dados dos questionários, aplicados aos alunos, a utilização e comportamento frente às TIC no Ensino Médio Inovador e no Ensino Médio Tradicional. A análise realizou-se à luz do referencial teórico de alguns estudiosos da área das TIC como Moram, Ferres, Prado e da área da aprendizagem: Vygotsky e Moura. Apesar do resultado dos alunos que participaram do projeto do Ensino Religioso ser positivo e de alguns alunos mostrarem a sua inserção no mundo das tecnologias com fim educativo, percebe-se, também, que alguns jovens ainda estão com dificuldades de integrar-se neste mundo das TIC, desejam e buscam ajuda; outros desejam usar as tecnologias, porém não têm os meios e deparam-se com os problemas da qualidade do sistema tecnológico da Escola e com a falta de funcionários no laboratório para seu uso

Transportation and storage sector and greenhouse gas emissions : an input-output subsytem comparison from supply and demand side perspectives

We develop an input-output subsystem analysis based on the Ghosh model. Our method analyzes the interrelations in terms of emissions between the different subsystem subsectors and between the subsystem and the rest of sectors of the economy through the decomposition of total emissions into four explanatory components. In contrast to previous subsystem analyses based on the Leontief model, our method considers the emissions of the whole activity of the subsystem and not only those related to its final demand. This is particularly relevant to study the responsibility for emissions of the activity of sectors that produce mainly for other sectors. We apply this method and also the subsystem analysis from the demand-side perspective to analyze the transportation and storage subsystem in Spain in 2014. The activity of the subsystem induced the rest of sectors of the economy to pollute less than the emissions it was induced to emit. There are significant differences between the outcomes from demand- and supply-side perspectives, so that the consideration of both perspectives provides more accurate policy recommendations

Choosing Variant Interpretation Tools for Clinical Applications: Context Matters

Clinical variant interpretation; Healthcare costs; Pathogenicity predictionInterpretación de variantes clínicas; Costes sanitarios; Predicción de patogenicidadInterpretació de variants clíniques; Despeses sanitàries; Predicció de patogenicitatPathogenicity predictors are computational tools that classify genetic variants as benign or pathogenic; this is currently a major challenge in genomic medicine. With more than fifty such predictors available, selecting the most suitable tool for clinical applications like genetic screening, molecular diagnostics, and companion diagnostics has become increasingly challenging. To address this issue, we have developed a cost-based framework that naturally considers the various components of the problem. This framework encodes clinical scenarios using a minimal set of parameters and treats pathogenicity predictors as rejection classifiers, a common practice in clinical applications where low-confidence predictions are routinely rejected. We illustrate our approach in four examples where we compare different numbers of pathogenicity predictors for missense variants. Our results show that no single predictor is optimal for all clinical scenarios and that considering rejection yields a different perspective on classifiers.This work was supported by research grants SAF2016-80255-R from the Spanish Ministerio de Economía y Competitividad (MINECO), PID2019-111217RB-I00 and TED2021-130342B-I00 from the Spanish Ministerio de Ciencia e Innovación, and by the European Regional Development Fund (ERDF) through the Interreg program POCTEFA (Pirepred, EFA086/15)
