Qualitative analysis of matrix splitting methods
2001
Abstract Qualitative properties of matrix splitting methods for linear systems with tridiagonal and block tridiagonal Stieltjes-Toeplitz matrices are studied. Two particular splittings, the so-called symmetric tridiagonal splittings and the bidiagonal splittings, are considered, and conditions for qualitative properties like nonnegativity and shape preservation are shown for them. Special attention is paid to their close relation to the well-known splitting techniques like regular and weak regular splitting methods. Extensions to block tridiagonal matrices are given, and their relation to algebraic representations of domain decomposition methods is discussed. The paper is concluded with ill…
A Qualitative Analysis of Affect Signs in Telecommunication Dialogues
2021
There is growing evidence in the science of psychology that affective phenomena are not homogeneous and that their manifestations may vary across cultures and under the influence of contextual and demographic factors. Given that there is no clear universal expression of emotions and mood in human behavioral processes, it is necessary to continue to study the heterogeneity of the observed features in language and speech. This qualitative study analyzes the dialogues of 40 individuals in the field of telecommunications and, using a content analysis and phenomenological approach, describes lexical and non-lexical signs that could indicate features of affect. It can be observed that complete sa…
The Significance of Member Validation in Qualitative Analysis: Experiences from a Longitudinal Case Study
2007
This article explores the concept of member validation and its potential role in the process of constructing case descriptions and interpretations in qualitative research. Although generally approved as a required step in qualitative inquiry, the format, conduct, and purpose of this vary significantly according to different research perspectives. The paper discusses methodological and validity aspects of member validation, and illustrates these issues with experiences from member validation in a longitudinal, interpretive case study in an airline company. A definition of analytical abstraction as including three steps, referred to in the methodology literature as the "ladder of abstraction"…
Using Modelling and Tablets in the Classroom to Learn Quadratic Functions
2017
In this chapter, we present teaching material to work with a quadratic function and the meaning of its parameters through the mathematical modelling of a real-life phenomenon: the relation between the time and the height of a ball during a complete vertical rebound and fall. The teaching material uses electronic tablets to collect and process real data in the classroom. After analysing a year 11 implementation, we note that a qualitative analysis of the phenomenon and the families of functions and the students’ prior knowledge about these functions are key elements to manage and control the modelling process, especially, to choose the model and to interpret the results in terms of the pheno…
Qualitative analysis of team interaction in games by means of the load-performance-metamodel PerPot.
2006
Observation of team behaviour in games shows rather inhomogeneous distributions of the levels of activity and effectiveness along the game. It is to expect, of course, that even for a high level team a phase of great effort is followed by a phase of reduced activities, while the opponent team is increasing its pressure. The result could be thought to be something like a rhythmic change, where the maximum activities of the one team correspond to the minimum ones of the other team.However, as we got from handball data that Martin Lames from the University of Ulm/Germany recorded last year (private correspondence), the correspondences can be much more difficult and varying: Lames measured the …
Acoso escolar y Educación Física: una revisión sistemática (Bullying in schools and Physical Education: A systematic review)
2018
El objetivo de este trabajo es realizar una revisión sistemática de estudios sobre acoso escolar y Educación Física (EF). Se identifican, categorizan y analizan los artículos señalando sus características y sintetizando los principales temas de investigación y su contenido. Para ello, se ha consultado la base de datos Web of Science®. Se seleccionaron un total de 19 artículos científicos. Respecto al análisis documental, se presentan hallazgos sobre revistas más productivas, autores e instituciones con mayor actividad investigadora en este campo y metodología de investigación utilizada en los estudios encontrados. Además, se hace un análisis cualitativo centrado en el contenido de los 4 tem…
INVESTING IN SKILLS AND INNOVATION – NEW STRATEGIC TASKS FOR PUBLIC ADMINISTRATIONS
2014
Evidence shows that in the labour market the most demanded specialists are those with high-level vocational skills, implying also their competence for innovation. The latest EU policy initiatives explicitly call for innovation in vocational education and training (VET) systems. This is a relatively new VET policy development. At the same time, it is not yet sufficiently discussed how innovation in VET systems could be best translated in practical terms. Traditionally innovation has been related to the research and development domain, and little routine practices exist regarding the VET system. The present paper will explore the opinions and estimations by public administrators and experts r…
Appunti contrastivi sui verbi valutativi suffissati italiani e spagnoli. Analisi di due corpora sincronici
2019
italianoIn questo lavoro si espone uno studio contrastivo italiano-spagnolo sui verbi del tipo canticchiare e canturrear, solitamente denominati verbi valutativi suffissati (VVS) o verbos apreciativos. A partire da due corpora sincronici, si svolge un’analisi quantitativa e qualitativa delle forme riscontrate, al fine di determinare quali siano i VVS piu frequenti nelle due lingue in esame. Si analizzano, inoltre, possibili fenomeni di variazione lungo l’asse diafasico, diamesico, e diatopico, cosi come le caratteristiche semantico-azionali dei 25 VVS piu ricorrenti. EnglishWe present an Italian-Spanish comparative study on the so-called evaluative suffixed verbs(ESVs), such as canticchiare…
El aula de comunicación y lenguaje y la inclusión escolar. Dificultades y estrategias de intervención / Communicatio classroomn and language and scho…
2016
This research shows a case study of two students schooled in the Communication and Language classroom of a Valencian school. The main goal is to understand the situation of inclusive education of these students. With this aim, it has collected information through record sheets, interviews, surveys, informal conversations and field journal that allowed us to do a qualitative analysis. We have described the difficulties that hinder the transition to ordinary classroom and we have analyzed the correspondence between intervention strategies of both classrooms. With these results, we reflect on the accomplishment of the goal of creating C&L classrooms: the progressive inclusion in ordinary class…
Developing Science Observation Skills
2015
Acorn ants (genus Temnothorax) are a powerful model organism for illustrating the variety of interactions in an ecosystem. We developed five teaching units with acorn ants as the exemplary insect. The aim of this study was to provide a quantitative and qualitative analysis of secondary school students’ attitudes before and after teaching units. Students (N = 459) from 22 classes participated in the study. Students’ attitudes were measured using a two-stage test design. We investigated the influence of class level, gender, teaching units, and time period of participation on students’ attitudes. Additionally, we surveyed a subsample of students on their learning enjoyment in 10-minute intervi…
