Comparison of the environmental assessment of an identical office building with national methods
2019
The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The ?be2226? office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amou…
Energy efficiency in the European Union: What can be learned from the joint application of directional distance functions and slacks-based measures?
2014
Abstract Over the last few years concerns have increased about the energy mix in many countries. These concerns have been of greater magnitude for countries with a common energy regulation such as European Union (EU) member states. An important aspect to take into account when choosing a given energy mix is the efficiency involved in its generation. In this context, the present study analyzes the efficiency with which electricity and derived heat was produced in 25 EU member states over the last decade. This analysis considers not only the inputs and outputs involved but, more importantly, which undesirable by-products were generated during the production process, a relevant issue for EU cl…
Análisis de la adecuación de libros de texto de E. Primaria a la enseñanza a estudiantes de altas capacidades matemáticas
2013
Un problema al que se enfrentan los profesores de matemáticas de Enseñanza Primaria es la necesidad de hacer adaptaciones en sus programaciones para ofrecer una educación adecuada a sus alumnos de altas capacidades matemáticas. Las editoriales de libros de texto de matemáticas de estos niveles educativos ofrecen diversas soluciones que, usualmente, consisten en incluir, en el libro del alumno, algunos problemas más difíciles y, en la documentación del profesor, una propuesta de problemas de ampliación. Una cuestión que se plantea al analizar un libro de texto de matemáticas es valorar cómo de útil puede ser el material proporcionado por la editorial (libro de texto y materiales complementar…
Problems with variation: an educational experience of cultural transposition with prospective primary teachers
2022
The paper presents some theoretical reflections and some methodological notes about a Professional Development (PD) path worked out during the last two years by Italian researchers for prospective Primary teachers. The theoretical construct of Cultural Transposition defines the framework of the PD path's activities and the related research. It was used to define an interesting cultural lent to delineate possible new approaches for effective pre-service teacher education programs, in particular for the Primary level. The defined methodology was based on the possibility to reflect about the decentralization of didactic practices based on a specific cultural context through one or more contact…
Modeling Marginalization: Emergence, Social Physics, and Social Ethics of Bullying
2020
In this paper, we outline the construction and initial simulation experiment results of the Marginalization model (MARG). We experiment under different group parameters because the theoretical paradigm we follow views bullying as a result of social processes. Our primary research question explores the possibility of bullying emergence as agents select interaction partners in a university setting. Based on the simulated process, our results take indications of the stress of marginalization in a student group as a proxy for emer-gent marginalization. MARG simulates two types of interactions between pairs of students: forced and hang-out interactions. In the latter, students decide whether to …
The process of identifying gifted children in elementary education: Teachers’ evaluations of creativity
2012
This study describes the importance of creativity in the identification of gifted elementary-aged children and presents the process of validating a scale for rating the creativity of the students through the teachers’ responses. The results show the instrument’s unifactorial structure, satisfactory levels of internal consistency, as well as convergent and discriminant validity. The results are discussed in terms of their implications for the work of school psychologists.
Student outcomes in Philippine elementary schools: An evaluation of four experiments
1999
International audience; Policymakers in most developing countries are concerned about high dropout rates and poor student learning in primary education. The government of the Philippines initiated the Dropout Intervention Program in 1990-92 as part of its effort to address these issues. Under this program, four experimental interventions were randomly assigned to 20 schools in selected low-income areas. Pre- and post-intervention data were collected from these schools, as well as from 10 control schools, in order to evaluate the program's impact on dropout behavior and student learning. The economic justification for replication appears to be strongest for the interventions that provided te…
Glutathione in Cancer Biology and Therapy
2006
The glutathione (GSH) content of cancer cells is particularly relevant in regulating mutagenic mechanisms, DNA synthesis, growth, and multidrug and radiation resistance. In malignant tumors, as compared with normal tissues, that resistance associates in most cases with higher GSH levels within these cancer cells. Thus, approaches to cancer treatment based on modulation of GSH should control possible growth-associated changes in GSH content and synthesis in these cells. Despite the potential benefits for cancer therapy of a selective GSH-depleting strategy, such a methodology has remained elusive up to now. Metastatic spread, not primary tumor burden, is the leading cause of cancer death. Fo…
Volviendo a pensar la alfabetización a través de los métodos mixtos: un estudio desde la mirada de los alumnos, las familias y el profesorado en la E…
2020
Los métodos mixtos presentan una alternativa sobre la investigación de la alfabetización como un fenómeno complejo. Este artículo analiza la integración de enfoques cuantitativos y cualitativos para hacer inferencias causales entre la alfabetización como práctica social y los diferentes espacios de interacción. Este estudio se realizó siguiendo un diseño secuencial de métodos mixtos. La muestra estuvo compuesta por 1.540 niños, 1.438 familias y 74 maestros. El proceso de recogida de información combinó cuestionarios y procedimientos etnográficos. Los datos se analizaron mediante la realización de análisis correlacionales, modelo de ecuaciones estructurales para grupos múltiples y análisis c…
Motivational Climate and Students’ Emotional Experiences and Effort in Physical Education
2010
The aim of the study was to examine the impact of a self-determined motivational climate including support of autonomy, relatedness, task involvement, and ego-involving climate on students’ affective responses and effort in physical education. The sample involved 338 sixth-grade students (11–12 years old) who completed a questionnaire battery incorporating measures of motivational climate, enjoyment, trait anxiety in physical education, and effort. The results of the reliability and confirmatory factor analyses supported the psychometric properties of the measures. Multiple regression path analysis results indicated that task-involving climate, autonomy, and relatedness support had more pos…
